Something similar happened to me. Started at 281, got down to 148 by July of last year, which is when I stopped after leaving my job. Slowly crept back up to 173 after that. I'm back on sema now at a low dose, five months in and sitting at 167. Not losing anywhere near as fast as before, but just halting the climb feels like enough progress right now as I chip away at getting the number back down. For you, going back on sema sounds like the right move. Stopping the regain is really the first step. Sure, some of it came back, but you didn't lose all your progress, and you caught it and are acting on it, that counts as a win. It just shows maintaining is its own skill we're all still learning. Keep fighting for yourself.
