"So I've been smoking for five years. I have tried quitting 3 times in the past, with patches, gum, and cold turkey. None of that worked out very well at all. So I decided to try this out, and it works great! I have maybe one craving a day for a very brief amount of time then it goes away. DO NOT DRINK ALCOHOL while on Chantix. I'm not going to give you all the details but lets just say thanks God for good friends. So please don't drink while taking this medicine."
