r/MounjaroIn

I took my first shot of Mounjaro, 2.5mg, on Tuesday evening, and I was blown away by how quickly I felt a change in myself. The constant chatter in my head quietened down. The food noise disappeared. The porn spirals, the endless YouTube doom scrolling, all of it suddenly lost its grip on me. I felt clear-headed, calm, focused. It genuinely felt like something had shifted in my dopamine reward system, and that made me incredibly excited, especially because one of my biggest struggles is alcohol and not knowing when to stop once I start drinking.

Saturday was Eurovision night here in Europe, so a big night out. I was nervous about how my body would react to alcohol on Mounjaro, but at the same time I was really hoping this medication would help with my drinking patterns too.

I started the evening at my friend’s house where we had wine. Straight away I noticed something was different. I couldn’t drink quickly. I don’t even fully know how to explain it. It almost felt like an aversion, or at least a lack of desire. I was sipping incredibly slowly, enough that my friend even noticed. I had two glasses of wine, and then we went to the nightclub.

Normally by that point I’d already be quite drunk, but this time I felt strangely sober, definitely not feeling that usual buzz or rush I normally chase. And instead of ordering strong liquor like I usually would, I ordered a beer. That alone was already very unlike me.

Over the course of many hours I had around six drinks in total, and even then I still felt oddly “flat” towards the alcohol. Like the rewarding part of it just wasn’t really there. I longed and missed my outgoing alcoholic behaviour.. something felt “off”.

But then around 3 a.m. things changed. I started letting loose, ordered stronger drinks like gin and tonics, and the night escalated from there. In total I ended up having around 13 drinks all night and stayed out until the early morning hours.

I did have fun. I genuinely had an amazing night. But at the same time, the pattern was still the same: everything after 3 a.m. was not worth it. That’s always the part I regret. The part where the night stops being meaningful and just becomes compulsive excess. And that’s exactly why I was so excited about this medication in the first place.

What I do find interesting though is that Mounjaro still seemed to blunt the escalation. Even after the night spiraled, it only stayed with alcohol. Normally a night like that could spiral into other impulsive or self-destructive behaviours too, but it didn’t. It felt like the medication put some kind of ceiling on things. And honestly, I suspect that without that blunting effect, it could have escalated much further, like consuming other things.

Something else that really stood out to me happened the next morning. When I woke up, I immediately felt dread. That horrible “oh my God, what did I do, how do I feel?” feeling. Usually that immediately throws me into a shame spiral where I numb myself with porn, doom scrolling, and more compulsive behaviour. But this time I didn’t. I really didn’t. And I genuinely think that’s because of the Mounjaro. It felt like it interrupted the usual shame-addiction cycle enough for me to recover emotionally much quicker.

So I feel both encouraged and disappointed at the same time. Encouraged because the medication clearly helped in multiple ways. But disappointed because I had secretly hoped for an even stronger effect on the drinking itself.

I also realise part of this was me exploring and testing the waters. I wanted to see what this medication actually feels like in real life situations. And one thing I noticed is that because the rewarding “buzz” from alcohol felt muted, there’s a danger there too. Does that eventually help me stop because drinking no longer feels worth it? Or does my brain start chasing the missing feeling by drinking more and faster to force it?

That’s the part I’m still unsure about.

I’m also only on 2.5mg, which is a very low starting dose, even though I’m already reacting strongly to it in other areas like eating and compulsive behaviours. So part of me wonders whether the alcohol aversion would become much stronger at a higher dose.

What I found fascinating though was how real the aversion felt at the beginning of the night, the slow drinking, the lack of desire, and then how quickly it faded once my brain became disinhibited from alcohol itself. It was almost like the alcohol overrode the medication once I crossed a certain point.

But even then, something still held. I didn’t take anything else. It stayed just alcohol. And for me, that’s actually very significant.

What this experience really showed me is that Mounjaro is not magic. It helps enormously, but I can already tell I need therapy alongside it. The medication may quieten the compulsive drive, but I still need to work on the emotional patterns, the binge mentality, the “keep going” switch that flips in me after a certain hour of the night.

Hi everyone

I recently started Mounjaro/tirzepatide 2.5 mg and would love to hear from people who have been on it longer.

I’m 85 kg, 171 cm, BMI around 29, so just under the usual BMI 30 threshold. My main reason for starting was weight loss, because I’ve tried so many things over the years and always regained the weight.

But honestly, what really caught my attention was the addictive/compulsive side. I struggle with food noise, occasional binge eating, binge drinking, late-night YouTube spirals, porn, impulsivity, and that constant “just one more” feeling. It often feels like my brain is chasing dopamine and novelty, even when I know it’s not good for me.

I’ve only been on 2.5 mg for one week, but I’m honestly shocked. The effect on my impulsivity has been massive. I don’t feel that same pull toward all-night binges, scrolling, porn, drinking, or reward-chasing. It’s like the volume has been turned down in my brain. I suddenly have more space to do normal life things, like cleaning, seeing friends, and actually choosing what I want to do instead of being dragged by urges.

I know this sounds dramatic, but so far it feels like it’s helping with much more than appetite.

I’m not looking for medical advice, just real-world experiences.

My main questions:

1. Did anyone feel strong effects already on 2.5 mg, and did they last or fade?
2. How long did 2.5 mg work for you before increasing?
3. Did anyone stay on 2.5 mg long-term for weight loss or maintenance?
4. If you started around BMI 29–30, what was your weight-loss experience?
5. Did it reduce food noise, binge eating, alcohol cravings, or compulsive behaviors beyond food?
6. Did anyone notice reduced urges around scrolling, porn, shopping, gambling, drinking, or other dopamine-seeking behaviors?
7. Did the calmer, less reward-driven feeling continue long-term?
8. For people on it 1–2 years, did the effects weaken over time?
9. Has anyone used a “lowest effective dose” strategy successfully?
10. For maintenance, did you stay on the same dose, lower it, space injections out, or stop?
11. If you stopped and restarted, did it work the same again?
12. How did you manage protein, calories, weight training, and muscle preservation when appetite was low?
13. Looking back, what do you wish you had done differently in the first few months?
14. Did it help you actually change habits long-term, or mainly suppress urges while on it?
15. For addictive-type patterns like binge eating, binge drinking, scrolling, porn, or compulsive reward-seeking, did it feel like a cure, a tool, or something in between?

I’d especially appreciate answers from people who have been on a GLP1 (monjaro or whatever) for a year or longer, people maintaining weight loss, people who started around BMI 29–30, or people who noticed changes in food noise, alcohol, binge eating, porn, scrolling, or other compulsive behaviors.

Thanks so much.
