I was taking Chantix for a while too and think it's a great medication. I got down to about 5 smokes a day then all hell broke loose with AH and I quit taking the Chantix and bought cigarettes. Now that he's out of the house, I think I will try again.
I'm sorry for your loss too. Sometimes I feel like a hypocrite for complaining about Ah when I have my own little addiction going on to.
