Okay so I am weaning myself off of Effexor and onto Paxil. I am already experiencing some side effects like nausea light headed and am having second thoughts on this antidepressant. What should I do? All is I read is the negatives regarding both Effexor and Paxil. It seems withdrawing from Effexor is very hard. My Psychiatrist just prescribed the Paxil because I told him I needed change. I mean while on Effexor I still was feeling suicidal and depressed a lot of the time, so change is needed right? I really wish I did not have to be on medication! I hope the side effect of weight gain does not come up while I take Paxil, that will just make me stop taking it immediately. Anyone who takes Paxil, please give me your experiences with the drug. I really need advice.
