My most successful quits (aside from quitting for pregnancy) have come from times when I told myself I could still have a cig if I wanted it...I just didn't want it. I challenged myself to see how long I could go, and that worked well, too. So for me it was a "See, I've gone three days, and if I have one now that ruins the three days...but I can also just have one if I really, really need to and then start the three days again." I kept a pack with a single cigarette in it for like three months before I finally threw it out. But it really helped me to have that "escape valve," so to speak. So maybe you could do something like, keep him busy for a while, and then when he reaches for his smokes you could say something like, "You know, you've gone six hours without a cigarette. Want to see if you can make it seven?" and go on from there. You could maybe offer blowies for a certain number of hours/days, I mean, I don't want to get too personal, lol, but it's a real motivator for a lot of men.
