Champix blocks the receptors in the brain that are stimulated by nicotine. The longer they are blocked the better chance you have to quit smoking. There are reports of serious side affects with using this prescription so be careful with it. After my 3rd attempt using this I have been completely smoke free for 10 months after 40 years of smoking. I can't believe it myself. I DID IT!!
Discuss how this may help you with your Doctor. Good luck.
