my initial 7 days were pretty similar to what OP described — the food noise went way down, and one of the earliest changes i noticed was a big boost in my afternoon energy (before this, i'd crash hard around 2-3PM, usually right after a massive, awful lunch). since i wanted to start low and move slowly, during those first 2 weeks it honestly felt like 2.5 could have been my forever dose. that said, after 3-4 weeks at the same amount, the appetite suppression clearly got weaker, so i moved up just a bit more gradually than the standard recommended schedules (4 months in now, sitting at 7.5 mg). for me, i'm not too far from my target weight, and i'm okay with taking my time so i can limit muscle loss.
