Ok, I had the first jab yesterday. Very nervous. What can I expect in these first few days/ weeks? Anyone on here a bit ahead of me, please?

Hi all,

I have just done jab no 6, sticking with 2.5mg at the moment and have lost 10lbs so far. No side effects apart from slight headache now and again, however I must drink more, I can struggle with my water intake. My SW was 11.12. My weigh day is usually on a Sunday so hoping for that 1 stone loss soon. I have felt hungrier this week so maybe that’s a sign to up to 5mg when I order next. Does anyone else take extra vitamins? There’s so many so not sure which ones I should take? Thanks

4th week, ive lost 4KG (8lb) in total. I was on MJ last year for about 7 weeks and lost 12KG (26lbs) but I came off it for personal reasons. I feel my loss is steady away so I will be sticking with the 2.5 for my next pen - few side effects, heartburn, few headaches, dry mouth, constipation or a few times a little diarrhoea. I feel hungry but do not have an appetite if that makes sense. Trying to eat more protein, i'm starting to notice a little hair loss which i got last time but that stopped when I stopped MJ, its only very slight so not worried about that. Drinking between 2-4 litres of water a day

Due to do jab 6 tonight which is late! I started doing on a Tuesday but memory like a fish so will do tonight.
Happy so far!

Started 10 June but have had 6 shots; 4 at 2.5 and 2 at 5, and I’ve just calculated I’ve lost a stone 😀. Reason I hadn’t realised is our scales are in kilograms. 🙄
I’m over the moon 😀

Well done!

I'm 2 jabs ahead of you. But have had a bad week this week. Im tired, dh has been a knob, work has been crappy and I've not been as healthy with my meals.

I haven't gained but haven't lost. Which I guess is a positive. Just cross with myself!! I am an emotional eater though.

as an aside has anyone else found that injecting into your tummy doesn't seem to be as effective? I've got a fairly big apron following years of not eating well and being lazy but the jabs doesn't seem to curb my appetite when I inject there. Will be going back to my thigh on Friday!

Help needed.
so I have a syringe 1ml to get last dose out of pen. It’s probably more than a dose. How much is 1ml equivalent to clicks? Still on the first 2.5mg pen.

Ihatelittlefriendsusan · 03/08/2025 17:56

It's not a dose. Please dont do this.

Hey all! I would love to join you. I have my first order arriving today, and planning to start.it tomorrow.

Quite nervous and have ummed and ahhed a lot due to migraine and HRT but having had my online consultation was assured that my medication doesn’t prevent me from doing Mounjaro!!!

Going to catch up on all your suggestions in this thread and go my food shopping tonight in preparation!

Good luck on your journey 😄 I was on it for 6 months, done 2 x 2.5 pens and 4 x 5mg pens, i lost almost 4 stone. Took a break over christmas purely as i couldnt afford it but ive since started again, after a 4 month break I gained 7lb which I thought was going to be a whole lot more. Weighed in today and ive lost the 7lb and an extra 3lb 😄 what I will say is drink loads and when you think you've drank enough, drink more! Eat! Please eat. I dodnt for the 1st 2 weeks of mj and ended up with gastritis. Totally my own fault for being a moron and not eating as i wasnt hungry - lesson learnt! If like me your rubbish at getting fibre in i recommend a decent fibre gummie or supplement. Same with collegen. Im 39+1 and thought i was too young for collegen etc. No I need it or my skin just looks a bit meh and my hair thinnens. But the plus side is being 4 stone lighter, going from a size 20/22 to a size 14 being comfortable and choosing what I wa t to wear rather than wearing stuff coz it fits is still mad. I sometimes feel a bit imposter sydromey when clothes shopping, will still always reach for the bigger size somehow 🙈 i also feel like my mh has had a boost. Ive more energy too. So yeah what im saying is go for it!! Absolutely go for it. In 6 months time youl be soooooooo glad you did lovely 🥰 keep your eyes on the prize and remember why you've started on days your struggling. I promise its worth it. Good luck ✨️

Aw thank you JG1586 that’s so amazing - if I can do half as well as you then I’ll be delighted! And great tip on the water!!!
