That's exactly what happened here too. Started at the smallest amount and felt appetite suppression almost right away. Went from frequent binge eating to eating quite modestly, even less than during a period at a healthier weight. Held at that smallest amount for a few months but saw zero weight loss despite the habit changes. Eventually moved up a level and the weight started coming off fast, close to 30lbs over the following few months.
Got down to a good number but have plateaued since. Honestly, the plateau's probably tied to stopping a different medication and picking up a daily habit that's boosted appetite. Recently quit that habit, and the doctor agreed to bump the dose up further. A few more doses at the current amount before that happens. Hoping to shed a bit more before maybe scaling back down for maintenance.
