Bupropion
"Today I was looking up the side effects of Bupropion HCL 150mg. two a day. I have been taking this for depression & have found it working. I have the ability now to diet & exercize & I want to interact more.  So, as I am reading the side effects I notice that its also used to stop smoking. I didn't know this. I have smoked for 30 yrs aprox & thought I had just stopped smoking for no reason & without even trying.  I wondered why I had almost no interest in cigarettes any more, some days even forgetting to have a cigarette!  If I do smoke it's just 1 or 2 in the evening & not every day and the feeling I have  is not at all a craving. It's more like I will myself to have a smoke because it's what I do (habit), but I don't need one & hardly even want it!"
