"I smoked for over 43 years & have quit numerous times it took a cancer scare to convince me to get serious about quitting I visited the doctor to get a prescription for chantix,the nicotine patch I used both products. The patch was used for 60 days,and the pill for an additional 90 days so far I have been smoke free for the past 2 years yes I experienced some of those side effects but I worked through them. I thank the makers of chantix for my successful 2 years."
