"Chantix worked for me. I smoked a pack a day for 35 yrs. Neither patches nor gum was affective. They made me feel ill really. Less than month on Chantix made me a non smoker. That was 7 yes 7 grateful years ago. It is amazing how much I missed out on with family and friends because I was out smoking. Not any more!  I am now there to hear the  joke or the wonderful story and amazingly I am also there  to share my life. And I have moved into the present because I am present."
