Bupropion
"I have been taking this med almost for 2 weeks. I was extremely skeptical, because of everything I have read and heard of this med. I have been smoking since I was around 18yr., I'm now 30. Anyways, the first 3 days were rocky and I almost quit taking, but realized it was just my body adjusting. It has had a positive affect, no adverse side effects, just mild like: dry mouth and tired. I don't recommend for someone who has severe depression or other psychological issues that could cause adverse effects. I take 150mg 2x a day. I do not use any other nicotine replacements. I do not go to therapy. Lastly I haven't had a cigarette in 3 days."
