I was on the pills for a bit over a year - they helped, but I just felt like they took the edge off of everything The highs as well as the lows. So basically, it helped the depression, but I wasn't particularly happy either and couldn't seem to give a damn about anything. That and they made me tired, I gained some weight that I'm still trying to get off now, and not all of the plumbing worked quite right if you get my drift.
I quit em cold turkey (not the reccomended method) with no problems last fall. My life situation has stabilized some, and I still occasionally have some problems, but overall I'm good now. The pills helped me through the rough spots, but I don't think I'd want to be on them long term.
