If the doses you're using work, I agree you don't need to go up, but most people don't respond that just strongly to 1mg or fewer of reta, so my worry about tiny starting doses taking forever is also fair. Feeling full just at least sometimes after smaller meals is certainly a GLP drug effect & a strong sign it's working, congrats, you might just be a super responder. Hunger effects seem a bit inconsistent, though I suspect that resolves at higher doses. Starting at 117kg & 1.87m and aiming for BMI 25 at 87kg is 30kg, about 26%, so at some point you'll probably need reasonable doses, somewhere between 4 & 12mg. But if just hunger control is good & loss rate is fine, there's no need to go up until those become issues. Watch larger meals, slow gastric emptying can cause gut issues.
