"I think he tells himself that it is impossible for him to quit."

I felt exactly the same way.....exactly. I had failed so many times and I even remembered a friend from back in my 20's saying she thought I would probably never quit. My Dad died of lung cancer, a straight up 3 pack-a-day Camel man at 53 when I was 23.......kept right on smoking! There wasn't a thing in my life I hadn't done without a cigarette. I smoked in the friggin' shower fer chrissakes!

Tell him urges pass. Try it. Don't substitute something for the urge like a cinnamon stick or knitting or whatever. Just continue to do what you were doing and the urge WILL pass. Quit thinking about it all the time.....just go on with your life (whatever is left of it).
