I don't see how smoking 1 every 4 hours if he plans to smoke 4 a day gonna hurt? Basically, if his plan for the week is 4/day; 16 hours being awake then it's 4 hours per cig. And yes, if you go over the allotted limit, you should punish yourself for it.
yea i just wanted to emphasize that if you go ver, you should get owned by your own addiction, not just "well ok just this once, 1 more cig"
just this once is never just this once.
