My pychiatrist has just added 10mg Paxil to my lithium, zonisamide, wellbutrin, provigil coctail to lift a persistant dark mood and anxiousness. My questions: I've heard a LOT about uncontrolled weight gain on Paxil. I already have a weight problem. Can I lose weight with diet and exercise? Also, is the withdrawal always as horrific as I've read? I'm concerned that if I show any manic symptoms I will have to get off the Paxil fast and it will be debilitating.
