Started 2.5 MJ on 25th Feb 2026 and had great success with few side effects. When i went up to 5mg the diarrhea and belly pain was too much over weeks so i went down to 3.3. I have been at 3.3 for months and still get diarrhea 48 hours after injection. Then i move to constipation by day 6 and 7, inject again and back to diarrhea. So far i have just accepted this and am happy to have lost 27kg on low doses. I am finding the foods I eat on particular days effect how severe the GI side effects are.

I mostly eat small meals and take de-gas and immodium most weeks to manage. I want to increase dose- last 2 weeks i have gone up slightly to 4mg and symptoms have worsened... usually only for one day and i have been home to manage however do i have to continue this every single week?

I havn't tried any other GLP1... anyone have advice please? Still have 20-25kg to loose.

Hard to believe I'm almost at the point of maintenance but here we are!

After 17 months I'm down 34kg and only have 4kg left until my actual goal (I've exceeded my initial goal but still have quite high body fat and that goal was just to get me in the low overweight range).

I had a consult today about maintenance and was told for every kg lost on Mounjaro, I'll need a month on a maintenance dose. So for me, this will be 38 months on a dose that suppresses my appetite (that dose is TBD). Apparently this is the advice coming from dieticians now.

Is anyone on maintenance dosage and been told the same thing? Or how long did you need maintenance doses for? Another 38 months is a massive expense 😬

Hello, I had great success of very small doses (the side effects were so so bad) but the last 6 months I’ve just been stuck on no weight loss (and a bit of a gain) life has been all consuming so i definitely know food and exercise have been inconsistent but now I have a deadline o want to meet for my goal weight but I’m scared of increasing too Much because I can’t afford a week Off work again because of the side effects. This is probably just more of a whinge and need for solidarity. Last time I was at the doctor I was within 5kg of Goal so we were talking about what happens when I reach it but it looks like I’m never going to get there

Hi I posted in here previously with various questions, ive edited this post as i un-intentinly broke a group rule so ive edited my post andcre posted.

Over all im doing pretty well and not complaining, had various side effects along the way but navigating as they arise from previous advice in here..

I've been on Monjaro for about 22 weeks now I've dropped about 28-29kg, starting weight about 119.5, 51 yr old male. Started on 2.5mg well, lost a fair whack and it did everything its intended to with no food cravings or cravings in general, but when it stopped working I went to 5mg on my GP advice, after about 7 -8 weeks on 5mg I went to 7.5mg again on my GP advice.

At the tail end of 5mg I struggled with hunger cravings and some sweet cravings. Moved up to 7.5 in my GP advice and been on it for 7 weeks. Most recent dose Sunday. Again getting sweet cravings( always had sweet tooth ). Weightloss tapered of last 3 doses of 5mg and again last 3 weeks on weight tapered off 7.5mg dose and food, particularly sweet cravings are back... have a script for 10mg from my GP to go up and is natural progression of drug, but not sure if I should persist on 7.5( cost wise) or jump to 10mg.

Ideally like to lose maybe another 5-6kg based on my bmi recommendation. But is a substantial jump cost wise( been using up my 5mg repeat scripts more regularly), I know 7.5 pen and 10 pen the same cost wise but wondering can I lose what I want and as cravings creeping in again and is a pattern, am I better off biting the bullet for next dose up as my GP suggested to manage sweet cravings and hunger thats creeping back in or be persistent with 7.5mg or even just except what I've gained and go back to a maintenance dose.

Has anyone else experienced sweet cravings between doses that disaoear when you ho up a dose or will the cravings just persist at each level increase if anyone has experience with this.... when yiu go back to a maintenance dose do cravings g's persist ?

Has anyone else had similar experiences re sweet cravings and hunger cravings with weight tappering off between dose increase?

Thanks in advance for your thoughts..

Not looking for Dose recommendations, more about the cravings i experiencing and has anyone else had similar. How did they navigate etc please.

Hey everyone

I’m on my 3rd month of Mounjaro (2 of 2.5 and just done my first jab of 5mg). I haven’t been having super bad side effects just the occasional nausea and stuff.

But since I started taking Mounjaro VERY occasionally I would wake up very early in the morning with a sudden wave of nausea. I usually force myself back to sleep but sometimes I do go to the toilet and you know #2. I usually feel much better then. I have changed my diet so I am not eating fast food but specifically last night I ate air fried salmon and tofu. Is that a cause of nausea?

I only am asking for advice since it’s waking me up. It ruins my sleep and I can’t sleep properly after that and I am hoping to see if there are more people who experience this and have any solutions or if this is not normal?

I started mounjaro in March weighing 105kg. 55 f. On September 19th I weighed 87.3 kg. It has been a journey. I am still on 5mg.

On September 21st I fractured my ankle. It turned out I needed surgery.

Surgery for me happened yesterday. The interesting things are you require a 24 hour fast rather than a 6 hour fast to make sure gastric emptying occurs. The anaesthetist took an ultrasound of my stomach just to say if my stomach was empty - which it was - but by that stage it had been 28 hours without food.

I was weighed with a moonboot on for surgery - I weighed 83.2 kg. I am allowed to take mounjaro whilst on the prescribed medication for pain relief.

It has been a journey. I am so grateful that I was significantly lighter when I did my ankle (carrying a washing basket down the stairs and missing a step!!!). I can hop around in a frame and crutches for a short distance - and can manage myself much better because of the weight loss. It honestly is the best decision I made for myself.
