I'm 4 months into taking mounjaro and have lost 2 stone. I did a month on 2.5mg, then 2 months on 5mg and I'm now on my first 7.5mg pen. I'm finding no difference on 7.5mg, food noise is definitely there, I'm craving chocolate and crisps and eating a fair bit. The only side effect I've had is hair loss. I remained the same weight for about a month. I did have side effects intially when I went up to 5mg but no change going up to 7.5mg.
I want to go up to 10mg on my next pen but I realised I'd be only a week into it and doing my second jab on it when we go on holiday for a week to Spain. I want to enjoy the food and worry I might be feeling dodgy if I react to the increase. I won't know until I start though. I could continue on 7.5mg for another pen but that's another 6 weeks on it and I potentially won't lose any weight and be fighting the cravings. Tricky!
