I just don’t think mounjaro is for me…

I am on week 5 of MJ (first week of my 5mg jab).

And honestly, I don’t think I can do this.

I’ve been suffering from disgusting regurgitating of food / burps, and I know that’s because I’ve made the wrong choices before / on jab day.

However, I am just sat here, thinking, worrying, catastrophizing about what I am going to eat. I have a busy social life which involves eating out and I am now worried about feeling ill.

I love food and it brings me enjoyment, and I know that’s a massive reason why I have become obese in the first place.

But, now on 5mg I don’t really want to eat, nothing is taking my fancy. I feel tired and I am badly constipated. But I know I need to eat because that will make me ill. And all of this is making me anxious.

I don’t really know what I am trying to say. Has anyone else experienced similar feelings?

Moving up to 5mg was really rough for me too if it helps at all. I had no desire to eat and burps were the worst, plus I got serious irritation at the injection site. It did calm down over the course of the pen and I’ve decided not to go up a dose this time to let it settle, plus I’m still losing so don’t need it.
With the not fancying anything to eat that’s kind of the point! It gives you the space to set up systems to make good choices. You really can’t afford to goby what you fancy (as you say that’s how you ended up here). I’m exactly the same, but I’ve accepted I can’t go on like that. You need to age the decision for yourself.

if you don’t want to eat it would suggest that 5mg is too high a dose and the first thing to try is going back down to 2.5mg. Drink plenty of water for the constipation. Regarding eating out, if you know where you’re going can you check out menus in advance and find a couple of options that are healthy/small so you know what you c an order? Rather than worrying about it and then stressing when you’re there.

And of course you can just stop taking Mounjaro if it doesn’t suit you.

No but then I never really had takeaways or ate out as much after covid really, so it's not affecting my social life.
There's not much to think about, just avoid fatty greasy foods and some react to heavy carbs like pizza or pasta, but not everyone does.
I've been ill twice in 11 months and both times was after half a pizza. I've never had pasta throughout as don't crave it anymore but a few have reported it causing GI effects.
Best thing to do is drink plenty of water as WLI dehydrate the body which could be causing the constipation and apso if you arent eating enough food, eat little and often so stop eating as soon as you feel full. I actually did go out for lunch one day 2 weeks ago and ordered a kids meal from chiquitos and that was fine. Also maybe a starter instead of a main is a better option.
If you stick to protein and veg you might find that better with burps etc. I've never had burps or vomiting or constipation etc so can't advise but I always stop eating when I'm full so don't stretch my tummy in that way.
It's almost 1pm and I've not eaten or drank anything yet as full suppression with jabbing yesterday morning, just about to have a coffee then will eat when hungry. So listen to your body and you will be fine.
Since you've just gone up to 5mg it will feel strong for a week or 2 but should settle down. You could always leave it longer before you inject next and do a smaller dose by counting clicks so 3.75mg.
Why did you go up to 2.5mg? If it was ok go back down so you can eat more. I was fine upto 12.5mg but did find them strong when starting every higher dose and had no appetite and nausea but then they settled down.
You can just stop if you'd prefer to do that or try wegovy if you want to.

I abandoned it at 5 weeks - sticking to the principles though and do 5 days at 1200 cals 2 days at 1600 cals ( weekend wine) and am losing at exactly same rate - I didn’t like the feeling of it - felt like I had morNing sickness constantly and3 days a week of heartburn

I stayed on 2.5mg for 10 wks then went up to 3.75mg for 5 before I finally went onto 5. Sounds like you perhaps moved up too soon. I’d drop back to 2.5 next week.

The loving food and gaining enjoyment from it is a big thing. I also love food and it was how I self soothed. I loved going out because it was an excuse to eat loads. Whenever I felt down I’d think about what I could eat. As a result I was fat and hated the way I looked. (Total denial about the associated health risks!) Starting MJ was hard because it took that ability to soothe myself away. I still do sometimes feel life is a bit empty without a tube of Pringles to fill it but I realise now I need to find other ways to stimulate my dopamine receptors because the food wasn’t good for me.

I still eat out but now the focus is on seeing my friends and enjoying getting dressed up. I do enjoy the food but I stop as soon as I start getting full. I can’t tolerate much alcohol at all on 5mg but could drink fine on 2.5 and 3.75.

if you are truly happy being over weight then MJ is definitely not for you. But I think it’s also possible that you are feeling the effects that I did of needing something to fill the gap that food has left. If you can decrease your dose and get side effects under control then perhaps you can find other rewards for yourself… Good luck whatever you decide.

5mg often takes a couple of weeks to adjust to. It did me, and I’ve had no issues since, I’m now in maintenance.

if you know you’re making bad food choices, then make good ones, that’s the first step, take a daily psyllium husk in the morning, with a litre of water, before anything else, ensure you eat a low fat high protein diet, lean proteins, veg, eggs fruit, salads etc, and just reset with a healthy clean diet.

eating out is fine, just eat the same stuff, seafood, grilled fish, steak, chicken etc, veg, salad, and eat a portion till you’re full, limit alcohol.

but you need to be in thr right mindset, if you feel resentful of that snd don’t want to, then come off, till you are ready, as the drugs don’t do it for you, you need to put thr work in in terms of healthy choices, and to eat thr right about of cals, eat your protein and work out. Otherwise you’re just going to regain and cause ill health, so wait till you’re emotionally ready.

MOunjaro isn’t for you if you don’t want to change your habits. You’ll need to switch out unhealthy food, bring in more protein and fibre, reduce your calorie intake to a deficit and then weight train in order to increase muscle mass and avoid muscle loss. Otherwise you’ll end up with other health concerns and likely just gain all the weight back again. Which is apparently very common anyway.

What it does do is treat a range of metabolic issues and reduce food noise to enable the above, so that you can stick to it. It’s really up to you.

Op

You do not have to move up a dose every 4 weeks. If 2.5mg was working for you then you should have stayed on it a bit longer.

I did not jump from dose to dose. I’m 1 year on Mounjaro and only just considering moving to 7.5mg. I have a really good balance or feeling slightly hungry but being easily full and no other side effects
