Comfortable weight?

b ✨
Okay so, I am 5'2" and recently dropped to about 89 lbs. I wasn't eating and I wasn't hungry. I've been prescribed an appetite stimulant. Let me tell you, it WORKS. I've gained like 6 lbs in 3 days. I'm at almost 95 now. I just want to know at what point I should wean myself off the stimulant. If you're also 5'2" (Or whatever you are!) What weight do you feel most comfortable at?
