Bupropion
"I've smoked from age 17 to 33. I've tried the gum, cold turkey, exercising and eating right to stop the cravings. After a friend told me about her experience I had to try it myself. I've been on welbutrin for 10 days and I feel amazing! I've had mild side effects such as insomnia the first 3 days and a few weird dreams...but after the 5 day I felt like a new person. I have no craving to smoke and my anxiety level to smoke during a stressful situation is tolerable. I recommend this to those who need help with quitting smoking."
