Glad to hear your success and my wife will be thrilled. She is a pharma rep for Pfizer and Chantix is one of her drugs. I wish I could just send you some but that isnt gonna happen without her killing me. LOL
Anyway, I assume by your comment you do not have insurance. If you do most insurance companies will jump at the chance to pay for chantix. The cost to pay for chantix is so cheap considering all the medical issues smoking costs.
Good luck, I do recommend staying on it for a little longer than 3 weeks but dont think you HAVE to use it for 12 weeks.
