Bupropion
"Finally decided to get serious about smoking cessation so my Dr put me on 150 mg 2X Daily of bupropion. I don't get all these people saying it increased sex drive, since it completely destroyed mine. Less overall interest, impossible to maintain an erection, next to impossible to orgasm my wife of 30+ years has been a hero through this and has really extended herself to help me get "there"). I have to agree with an earlier post regarding the validity of these comments. I can find not one shred of SCIENTIFICALLY documented evidence suggesting that sex drive or ability to orgasm is increased when only taking this drug for help stopping smoking. Guessing it must be pharm. reps writing these reviews."
