My first injection was 2.5 mg three days ago. A bagel came right before it, and at my next meal I my portion was noticeably reduced. Since then Ive barely felt hungry, but I still nibble tiny portions now and then. Because Ive been eating so much less, it took two days for a bowel movement, though I was completely regular before. Ive felt slightly tired too, though I might just be under-hydrated. No other side effects so far. My stomach may growl, yet hunger itself is absent. This morning at breakfast, a first, I hit a point where I really didnt want another bite, and it was already a far smaller portion than normal, like on day one.
