Yep, been smoking for almost 30 years now. You don't want to be around me if I haven't had my nicotine and/or caffeine. I freely admit I'm an addict. At least it's better than the drugs I used to be addicted to.
I used to smoke. I started when I was 15 or so, buying them from a C-store in a podunk little town. I smoked a pack a day up until I was 25ish. Then I finally mustered up the will power to quit the little buggers. Its a very hard addiction to break, but once you make that mental transition its easy to stay away from them. Of course, the main reasons why I quit was to feel healthier and save money. Four years later, I still feel like crap and I'm broke LOL!
