I had my first ever dose at 2.5mg a couple of hours ago. How long after the injection would side effects start? I injected into my thigh. I’m mostly nervous about nausea and vomiting.
I'm finding the more weight I lose, the more easily I feel the cold. I use to be someone that rarely felt the cold, but this winter I've been bloody freezing.
I’ve been on a GLP-1 medication for eight weeks now and I’m still on the starter dose of 2.5 mg. So far, it has been working really well for me: I’m losing weight, I have much less food noise, and I find it easier to make healthier choices. I’m also going to the gym regularly, so overall I feel like things are moving in the right direction.
One thing I’ve noticed is that it seems to have reduced my alcohol intake too. I used to struggle with binge drinking, and compared with how I used to drink and behave on nights out, I would say my alcohol consumption has probably reduced by around 50%.
At first, it felt like the medication really took away the desire to drink. I just did not feel particularly interested in alcohol. But I’ve realised that when I’m out in certain social situations, there is still a learned habit there: ordering drinks, staying out late, and chasing that buzz. So it has helped, but it definitely has not completely switched that part of me off.
What has surprised and frustrated me is that although I am drinking less, the after-effects seem much worse. For example, last night I went out around midnight and stayed out until 5 a.m. Over those five hours, I had six standard drinks in total: two beers, one shot, one double gin and tonic, and one single gin and tonic.
I went to bed at 5 a.m. and woke up around 10:30 a.m. feeling extremely dizzy, still drunk, nauseous, exhausted, and with a really bad headache. I was so wiped out that I went back to sleep. I spent most of Saturday asleep or dozing on and off, briefly watching YouTube and then falling asleep again. I got up late in the afternoon to eat something, then went straight back to bed and slept through Saturday evening into Sunday.
It genuinely felt as though I had lost an entire day, even though I had only had six drinks. I was invited to a few things on Saturday and had to miss all of them because I felt so awful. It is strange because I am drinking much less than before, but it feels as though alcohol is affecting me far more strongly now.
Has anyone else experienced this on GLP-1 medication? I’m grateful that it has reduced my drinking, but part of me wishes it worked strongly enough that I simply did not want alcohol at all, or that I could comfortably stop after two or three drinks.
I also wonder whether a higher dose would help more with alcohol cravings. At the same time, 2.5 mg is already working for me in terms of weight loss and appetite, so I do not feel like I should increase it just for that reason.
I started Mounjaro two weeks ago but I don't feel any effects yet. Is that normal? I'm on 2.5mg, and was hoping to stay on that dose for a couple of months at least.. do I just need to wait for it to build up in my system? Next shot is due Wednesday.
Hey guys just thought I’d share this because I didn’t wanna gatekeep.
I’ve struggled with weight loss for so long and it’s honestly been such a hard thing for me. I’ve been bullied for my weight before and it really messes with your confidence. I know a lot of people here probably understand how exhausting it gets when you feel like you’ve tried everything. I recently came across this service called Docaroo.com.au. They’re new so their consults are super cheap atm and they gave me a Mounjaro prescriptions asw. No mods I’m not promoting or anything, just thought if it would help someone out I’d share it here. Also if anyone knows any other places that are cheaper or better please let me know because I’m still figuring it all out too :)
I slipped a lot this week. I had a rough couple of days at work early in the week and fell into old habits and got some of my comfort foods. I managed to refocus on Wednesday and pull myself back together.
This week's stats and observations:
• Still on 2.5mg and have another 2.5mg pen left - side effects are gone and food noise and hunger are coming back strong from Friday - Sunday which gives me a chance to exercise my willpower.
• SW 89, CW 82.9, down 1kg this week.
• First 4 weeks I lost 4.7kg, second 4 weeks I lost 1.4kg.
• I have not been exercising or hitting my step goal. I feel like this is the hardest part for me and open to any and all tips on how you finally made yourself just do it!
• No alcohol at all this week. I am feeling so much better when I don't drink - I haven't had much alcohol at all since I started and each time I do I feel awful.
• I didn't track my calories for half of the week - I have been eating the same meal prep so I know in my head what everything is. But I plan to start again this week regardless as I like having the data.
This week I take my progress photos so I'm looking forward to that! Hopefully I will see a little difference :)
As amazing as it was to lose so much in the first 4 weeks, it definitely set my expectations high for how much I could lose. Seeing that drop to 1.4kg was mentally challenging. I know this is a process, I know that I still have better habits to form, I know that it doesn't matter if I hit my goal in 3 months, 6 months or a year if I haven't built those good habits.
It took me 20 years to gain this weight (most of it in the past 6 years). I will get there eventually :)
Hey all. I’m on 3.75 dose on 5mg pen. I’ve got little bits left from an old pen and they said just to keep in fridge. I don’t have insulin needles on me. So today for my dose can I do say 50/50 out of two pens and do I just do two different injection sites? Gotta take dose very soon!
Is anyone else struggling to reach your food protein targets, I watch my wife struggle to eat now, and the struggle upsets her, how is everyone else coping with this?
Sam Wood has just launched a new business that will be fitness with GLP telehealth support and I’m a bit torn.
He apparently has come around on the science of obesity and wants to support people.
I can’t help wondering if it’s just another cash grab and deep down, he and other fitness influencers that are and will make a similar move, still believe in dated science and diet culture.
What do you all think about influences moving into this space when they previously were some of obese and overweight people’s harshest critics?

ETA: Here’s the podcast episode (hadn’t yet listened when I first posted.
Hey All. Has anyone recently got a 15mg pen with the golden dose? If so, which pharmacy and which batch number?
My last 15mg pen with the golden dose had a batch number of D942497.
Any assistance would be great. Thanks in advance!
Hi, I am from Tasmania. I want to start using this as to help me with my weightloss (obese). Could you please recommend a clinic or doctor that won't judge me if I requested to take this. I want a doctor that needs my lab tests before prescribing the MJ to me, so I will know it's safe for me to use it.
I don't have medicare, just private health but doesn't actually cover the medicine. So, a doctor/clinic that is open to prescribe me a bigger mg to save more.
Thank you.
I had my third shot at 2.5mg and weigh in this morning, and the scales had gone up by like half a kg which isn't much, but wasn't what I was hoping for.
It has been a more sedentary few days the past few days since I hurt my back, but Friday, Saturday, Sunday were massive cardio days and low calorie and I needed recovery.
Just confused. Intake is definitely down. Hunger suppression fades by like day 5 but still not eating as much. My diet was already super clean and healthy.
I wanted to come back and update everyone because so many of you took the time to reply to my original post.
When I wrote it, I’d just completed my first week on 12.5mg and had only lost 0.34kg (0.75lb) that week. At that point
my stats were:
Started Mounjaro: 29th December 2025 (officially January 2026)
Starting weight: 29 st 11.4 lb (189.8kg)
Current weight then: 29 st 0.25 lb (184.3kg)
Total loss then: 5.5kg (12.1lb)
I genuinely felt deflated. 😪
Fast forward two weeks…
I’m so glad I stuck with it.
Current weight: 28 st 7⅝ lb (181.3kg)
Loss since my last weigh-in: 3kg (6.6lb) over two weeks — my biggest loss since starting Mounjaro.
Total loss since starting: 8.7kg (19.2lb / 1 st 5lb).
If you’ve found this post because you’re feeling exactly how I felt… you’re a slow responder, you’re eating less, tracking your food, doing everything you can, yet your losses don’t seem to compare with everyone else’s… please don’t give up.
Let’s all hang in there. ❤️
Everyone responds differently. Please don’t assume Mounjaro isn’t working just because your journey doesn’t look like someone else’s.
For me, 12.5mg has given me my biggest loss so far. Looking back, the same thing happened when I moved to 10mg—the first week or two wasn’t particularly impressive, then the bigger losses came afterwards.
I’ve also booked an appointment with my GP for a hormonal check. I’m going to ask about metformin, as I’ve had irregular periods for years, have been plus-size for most of my life, and I’m wondering whether insulin resistance could be playing a role. If my GP prescribes it, I’ll definitely come back and update everyone on how it affects my weight loss.
I honestly can’t explain how happy I feel today. 🥹
Thank you again to everyone who replied to my original post. Your encouragement genuinely stopped me from losing hope, and I wanted to come back and let you all know that you were right.
Patience really did pay off. ❤️
Hello , I'm diabetic who has been prescribed mounjaro for weight loss . ( Sugar levels is under control ).
I was planning to start with 5mg instead of 2.5 mg.
Need suggestions and advice whether I should do it or no
Hello all!!
Just had my first jab of 2.5mg of MJ this morning.
For background
In February 2024 I started on Ozempic (Wegovy wasn't a thing yet) and lost 30kgs (from 90kgs to 60kgs) in 14 weeks. I was bedridden, violently ill, no energy, couldn't eat for days at a time etc. Obviously it had it's intended effect, however it ws not done healthily.
Currently I am sitting at 69kgs and want to go back on to get back to 60kgs where I feel healthiest.
Can anyone recommend apps to track macros? I don't want it to be like last time I want to meet protein goals.
What apps are we using to track weight?
Any type of app recommendations to help me manage would be great!!
Welcome to hear any advice on this new journey on MJ
I went the doctors today and weighed myself after 2 months on 2.5mg of Mounjaro. Unfortunately, I was the same weight (maybe one kilo down)! The funny thing is that I'm sure my pants feel looser and I have definitely been snacking less on sweets. My food noise and cravings have been reduced. I'm going to start on 5mg next week, and I hope that I'll see more weightloss. I feel a bit disappointed as I had been trying to eat better.
Hello :) I’m just wondering if this clear protein is a good choice to help boost my intake?
Any advice is appreciated :)
Did you prefer to take your first and then subsequent weekly dose in AM, mid way through the day or right before bed
I sorta count my maintenance start as March 1, but I guess it started a little bit earlier. In any case, it's much easier to math from the beginning of a month so let's use that 😄
Many of you probably seen me post here throughout my journey, but a quick rundown is I started in November 2024 at around 152 kilos and hit maintenance in March 2026 at around 90 kilos. Highest dose was 10mg for a few weeks (I have to double check but it's somewhere around 6-7 weeks), but have mostly been on 7.5mg.
Overall I've enjoyed maintenance. It's freeing being able to eat more and not being so strict, but I've loosened the reins a bit too much I'm afraid.
Over the last couple months my weight has slowly but steadily crept up. I've gone from a low of 88 to a high of 94 as of today. That number is a bit inflated, but nevertheless my 'real' weight is somewhere around 92-93 kilos.
Overweight BMI for me starts at 94 kilos so this is my 'red line'. This month I am going back to logging every day and I'm going to cut out the snacks. Goal is by the end of this month to see 90 kilos on the scale again.
What I am learning is that while I do need to eat more, I also need to eat smarter. I had said no for almost 18 months straight and it was honestly nice to start saying yes to things. Saying yes once in a while is fine, but for me it's turned into yes every single time and that's due to me changing my environment and buying more snacks and such to keep in the house. That's changing today.
I'll post an update again perhaps around the 6 month mark as I'll hopefully have good news by then, but let's see how it goes. This is a stage 1 intervention, if this move doesn't go well I'll go up a dose next month. I'm just avoiding it as I always have side effects during titration and I just don't want to deal with it again.
As I mentioned earlier, overall I've been enjoying maintenance. I've had low level fatigue for some time and that's steadily improved as I've stayed in maintenance. I've realized a lot of it has to do with fueling, not just the medication.
At my starting weight I was rather inactive and had little to no energy to do anything so I didn't have to pay much attention to what or when I ate. I felt the same. Now, I've slowly realized that I need to eat a couple times a day to keep my energy levels up. If I go too long between meals, aside from feeling hungry of course, I notice I get drained so easily. Especially if I'm doing something physical. Making this connection has taken me far longer than I'd like to admit to realize.
Now that I've realized it, I feel a lot better throughout the week and throughout the day too. I don't dip towards the end of the day and just feel good consistently. Increasing my fluids has also helped with this general feeling of wellbeing.
Reaching this equilibrium also means I have mental space to do other things. Right now for example I'm trying to get back into running. Before I found it hard to focus on other hobbies as I have a one track mind and when I'm all in on something I can't focus on other interests. It's good not to have that overhead anymore.
Even though I'm at a technically healthy weight according to BMI, I have near obese levels of body fat according to BMI. I need to lose about 10 kilos of it to get to okay levels (sub 20% for a man), but closer to 15 kilos to get to optimum for a man (15% or so). Bit disheartening to realize how low body fat levels are for men to be 'healthy' but it is what it is. Of course, I can build some muscle so I don't need to lose as much weight, but even then I can only realistically put on 5-10 and that'll take years at my age.
Even though I've lost 60 or so kilos, the thought of having to lose another 10 or so feels overwhelming. To be honest, I sometimes wonder now that I've lost the weight how I even did it in the first place. Seems like a miracle that it could ever happen. In any case, I'm firm with not going at it again until next year. This year I just want to relax and enjoy maintenance a bit and develop other interests. This month is a slight exception as I need to get back on track, but hopefully I don't need to go all in as much as I just need to tighten things up slightly.
Anyway, that's it for now. I've sorta decided I'm repeating myself too much in the weekly threads I participate in so for now at least I'll do updates like this once in a while as I'm figuring this out so you'll see me here and in some other comments from time to time, but maybe not as much as before. Best of luck to you all wherever you're at in your journey!
Is it similar to those who are bodybuilding and they force themselves to hit their calorie goals?
Does it ever get easier?
I have to force my breakfast and lunch down - my protein shakes are saving me.
