From what I understand about Ozempic and friends is that it's not meant for super long-term use (I can't remember the exact time, like months to a year at most). Do you feel like that's reasonable? As in, do you feel like this is letting you form better habits that will continue after you stop using it? Or do you even have a feel for that (probably hard to guess how you will feel when you are off it)?
There have been long-term studies of semaglutide much longer than a year. I'm not aware of any finding that indicates that long-term use should be avoided. There is some indication that the weight loss plateaus within the first several years for most people, but the weight control and blood sugar control effects are persistent.
