Just started my journey, questions :)

Hello everyone! I just started my journey with the first injection done Thursday night. Starting weight 104kg, target weight 80kg 49y.o.male. The feeling is very good but I still have a few questions for the experts :) First, the feeling is good, too good to be true: I simply do not feel hunger at all. Yesterday I eat a small salad and just had 2 very small snacks in the entire day (I used to snack more than multiple times between meals) and today I do not feel hunger at all with any particular craving. I do not know how to express it but im somehow "worried" that for the first time I do not have much attraction for food (I guess it is normal though?).

Second question: I read a lot about hydration and yesterday I've been good at it but today I simply do not really feel much thirsty (to be fair I never been a huge water drinker). I am not the kind of person that sweat much, any suggestion on how to keep pace with it?

On the bright side, so far no particular side effect (mostly some air but not super much).

Thanks so much in advance to whoever wants to contributes with indications, suggestions to this!
