Been around the 5 year mark, since I quit. Hardest monkey I've ever had to kill. Smoked 2 packs of Camel non-filters a day, for many years...and I still miss them....but I've lost 30% of my lung capacity, and have COPD, so I keep reminding myself how hard it was to quit. I do miss an occasional big, old smelly cigar when I play poker with the boys, but I'm afraid that will get me started again too.
