Bupropion
"I have been on zyban just over 2 months. During the first month I smoked between 1 and 5 a day (I used to smoke 15 cigarettes a day). Now I don't smoke any. The most significant side effect that has caused me stress is HAIR LOSS. I am a woman and it is giving me a receding hair line and thinning at the hair line, plus I'm losing hair all over my head. To the point where I may need to stop taking this drug. I like the mood lift zyban gives me. It also gives me more energy and more focus to get things done.  I've had an increase in sweating, some loss of appetite, I've lost a little weight (I don't consider this a bad thing). I'm worried when the 3 months are up that a withdrawl may send me into a depression."
