Bupropion
"I'm very motivated to quit smoking so on day one with cigarette in hand at 3:43am, reading drug reviews, I give it a 10.   I seriously layed with my eyes closed listening to my husband breathe for three hours before I had to look up side effects...it appears that I'm not the only user still up.  The boost in energy was wonderful all day long. I will to continue to take it and will stop smoking. I never thought I was depressed, but today I feel like  moving and doing active things I would have laughed at yesterday, admittedly, that would be a life improvement. I am clinically morbidly obese due to my absolute love of food and tendency to binge eat. Today I have barely touched food. This May be the med for me for more reasons than I thought."
