Venlafaxine
"I have been on Effexor XR for 17 years now. I take 150mg once a day. My biggest negative side effect is extreme, excessive  sweating. I tried going off it earlier this year because I was fed up with this issue and thinking that maybe I really didn't need  it any longer. Bad mistake. Within 2 month's I was back at my Doctors a mental mess and was put back on it. I guess you have to take the good with the bad. Does anyone else have a issue like this while taking this med? It can be very embarrassing and makes me very self conscious."
