I smoke socially although I've been very good about avoiding tobacco in the last year. Every once in a while I'll have a cigarette or two at the bar. I only smoke Nat Sherman naturals which have no additives and actually smell like real tobacco. Plus they are like $8 / pack which discourages me from smoking them in the first place.

I smoked a lot more back when I dated smokers. And yeah, laying off the cigs when you're used to even just 4 or 5 cigs/day makes you cranky as all get out.

When you feel like a cig, go for a short ride, have sex, do some push ups, whatever it takes! Once you get through the first week though it gets much easier and you feel much better.
