Way to go!! I am coming up on 11 years smoke free and it is one of the absolute best things I ever did. I was a pack and a half a day smoker for years and I know first hand how hard it is to quit. One thing to consider would be to move to a low level patch at some point. That will get you away from the routine of inhaling anything and you won't have to look to that for any relief. Keep up the great work and stay strong!!!
