smoking cessation
"I started smoking at age 9. Smoking alot by age 13. Started driving 18 wheeler at age 23. Four to five packs a day depending  on whether I had to work 23 or 24 hours in a day. In Dec. Of 1999 I took Zyban for I think a month. From what I can remember , it made me a little nuts at times as well as violent. I understand it changes the addictive center in your brain but it changed my personality as well. The the second week I relapsed for one day and then none after that. Seventeen years and not one cigarette. Still wanted one once in awhile but never enough to light one up. I only wish I had done it sooner before my lungs went copd. Make no mistake, I would be long dead if I had not quit. (A coffee can full of phlegm a day)"
