Good luck with it. I hope you can stick it out. Smoking has never bothered me and I have zero health problems after being around two parents who smoked, and still do, while I was growing up. Mom smokes a couple packs of cigarettes a day Salem menthols the nasty shit that crystalizes the lungs. My dad is a pipe smoker and they are a rare breed nowadays. I smoked a pipe when I was in the USMC and my first couple years of college when I studied. Haven't smoked in years though. I used to chew tobaco when I was in jr. high and high school. I used to go through 9 tins of Coppenhagen and 2-3 pouches of Red Man a week for about three and a half years. Used to sit in class with a wad from cheek to cheek and swallow so I wouldn;t get caught and get suspended from sports.
Quit both cold turkey though.
