depression
"Y'all! -- I am one of these people who cannot say enough about bupropion! It has changed my life after only day 8. 

Such a subtle but powerful shift in perception and decrease in troublesome habits (smoking one of them, but also irrational anxiety getting on train, rushing down the street for no reason, rushing through dinner) has decreased by drinking, made me less weighed down. 

There are side effects the first few days but they will go away! Stick with it and you won't regret it ~"
