Bupropion
"i was given bupropion by my g.p. to quit smoking and for anxiety and stress.

i did the 150mg a day for 1 week and was fine,but after the first week it was time to double the daily dose to 350mg it was bad i could`nt control my thoughts or stop fixating on a task i was`nt myself at all.i went back to 150mg and after a week i just stopped smoking i knew that last one would be it and its been going on 4 months and i have`nt smoked you have to want to quit.

or never want to go through the hell of those pills again.give it a chance and stick with it.its hard but it worked 20+ years and i really feel better i don`t even think about it anymore even when people smoke beside me i just don`t feel the need anymore,its really amazing"
