WOW that's amazing how different people's experiences can be.

I smoked one pack spread out 2 or 3 days, for about 3 years (in college). Rarely would do a full pack in a day.

Quitting was pure torture. I stayed up 24 hours walking laps around my campus. Took like four full days for cravings to go away.

Haven't had a cigarette in 10 yrs. Occasionally enjoy a cigar without problems
