Quitting Prozac

Hello everyone I was once on lexapro for a full year it was great at first but I quickly gain some weight while on it and I was extremely tired that I would have to nap pretty much everyday after work as well no sex drive so I needed a switch. So here I am now on Prozac 10mg for one year as well it has been great still managed to gain a total of 30 pounds in 2 years. Which is not horrible but I’m having a very hard time trying to lose weight. So my psychiatrist prescribed Wellburtin 300mg and it did help curb cravings. However, it would make go to sleep late and as of now it has been affecting my work performance such as going late or calling off. I’m having a very hard time getting up in the morning. And I have been feeling really insecure about my weight. I have my psychiatrist appointment soon I’m at the point I want to stop taking them. So my question is how was the tapering process from Prozac? And was it easier to lose weight after getting off Prozac?
