My old man used to be a heavy smoker and packed it in in the 80s before all the patches and gum and other aids to quitting were around. What worked for him was working out how much he spent on cigarettes in a year and then he spent close enough the exact amount on getting something he wanted for the family, a video recorder in his case. Any time he had serious cravings he just thought of how he'd better spent the money and used that thought to bolster his willpower.
Good luck with it bud
