My husband and I started taking chantix the 1 st of December by the third week he had completely stopped smoking and he quit taking the pill (That was a mistake) I was only smoking 2-3 a day and kept taking the pill, well that continued for about 3 weeks and I stopped taking them also. This weekend he picked the cigarettes up and I find myself smoking more. Like today I've had Four and it's only 11:00 am. This morning were taking the pill again. My advice is not to stop taking the pill until your for sure that you've quit without a cigarette for alleast a month. I have to take the pill
