Has anyone used the drug chantix to quite smoking? My wife has been taking it for a couple of weeks now, she has cut down drastically (1-2 packs a day, now 1-5 smokes a day) but not completely quit. She wants me to try this so I thought I would ask how the success has been. I smoke 2-3 packs a day and I know I need to quit. Im not looking for any lectures that I need to quit, I already know this. Thanks
