smoking cessation
"Bottom line - it works. It will definitely make you quit smoking.   The side-effects are awful, but I guess its a price to pay for prolonging your life a bit.  
You MUST eat before taking it, or it sucks.
You need to try to be as stress-free as possible when using. You can't get into any conflicting situations. You might need to rely on a spouse or roomie to wake you up in the morning, or you will sleep like a rock and never acknowledge the alarm clock.
You can have some pretty gnarly dreams while using. You will quit smoking on this pill."
