Feeling Frustrated 😭

I started Mounjaro 2.5mg injections 5 weeks ago, no weight loss yet. I took my first 5.0 mg yesterday. (Aug 11th) What bothers me is, 4 weeks on 2.5 mg I didn't notice anything, still felt like overeating, always thinking about food and what I'm going to eat next. I'm hoping that the increase in the medication will change that. Also I'm really struggling to drink water. I've managed to drink 125oz a day but according to my weight I'm supposed to be drinking 200oz.. this is so frustrating 😭
