I quit on January 14. I take Chantix, and it is GREAT! No urges at all to have a smoke from the very beginning. I just hope that continues after I am off the pills, which will be in about 6 more weeks for a total of 4 months. If anyone wants to quit, believe me, this is the EASIEST way to go by far--a piece of cake, really. A bit costly, but well worth it.
