I chose celexa because it did not list weight gain as a side effect. Weight gain from prior anti depressant made me even more and more depressed til i quit. Been happily taking welbutrin for 7 yrs and normal weight until panic disorder began. Now i'm starting celexa and decreasing welbutrin. Should i ask my doctor to let me stay on welbutrin as well as celexa? Maybe in a smaller dose. Or regular welbutrin instead of welbutrin sr sge swithched me to a couple of years ago? Any advice will be appreciated!
