Not a doctor by any means, but if it was me I'd begin lowering the dose while watching weight and hunger signals very closely. I think you could land on a noticeably smaller amount that keeps you stable and just use the GLP to manage appetite without dropping any further.
I've hit my target weight now and am figuring out what comes next. Luckily I still have a large supply of Tirz plus some other items that caught my eye sitting in the lab freezer. My idea is to ease the weekly dose down from 15 mg while keeping an eye on the scale. If 15 mg weekly turns out to be what I need to hold steady, that's okay, but there's a real chance of going too far the other way. At 64 I don't want to become a frail old man who's too thin, and I'm only about 15 pounds from that point. It would be helpful to have a place for people to post about how they're keeping the weight off.
