ah yes GUM is in great abundance in the office and at home. Twizzlers is a great idea too - chewy and the right shape (well sorta)

.
Additionally, do any of you successful quitters have any advice for giving up those last 3-4 a day?? It seems like those are just the hardest for him to give up and I dont want him to be satisfied with simply cutting down that much and become a 3-4/day smoker.
You guys are great - thanks!
