I started Chantix 2 1/2 weeks ago. After 2 weeks I went to laser therapy and I quit. I am 72 hours smoke free. It is still hard but not near as hard as it has been for me in the past. This is my 6th attempt. I have tried everything from Zyban to Hypnosis. I don't know what is helping the most--the Chantix or the Laser. I do know that when the cravings hit, they pass quickly (thank God) and I don't get them all day. I also took out the book by Allen Carr from the library and just started reading it.........I am serious about quitting, huh
