Good job. Personally I've quit before and started back later, not because of addiction to nicotine, but that I ENJOY smoking. There's the whole hand to mouth fetish, and the lack of anything to do BUT smoke. I smoke menthols, so although you may not agree, it's rather a little different because I find if I go awhile without a cigarette I need a good mint. On one hand, quitting would certainly save me $15-$35 every week and a half, but on the other hand, I enjoy it so much and being surrounded by a smoking environment, it's pretty much pointless for me at this point in time. My father smoked for about 20 years, quit at age 35 cold turkey, I kind of see that as what my path may be.
cheers! or something
oh and btw to Rog - I quit drinking myself about 2 years ago(I never was a constant drinker, just one of those get real drunk every couple weeks types, I grew up surrounded by alcoholics), you can see how much better you do fairly soon, but you may find yourself in a strange position when you have friends who's main purpose on doing anything is to drink, drink first, or have a drink everytime they do something.
