good luck LT...cig smoking is a disgusting habit, and I gaurantee you'll be 10x better inside than you do now after you've quit for a few months!
just think of it this way...Thank God you're not having to quit a harder drug, like heroin or oxycontin or something...people go through NASTY withdrawal from shit like that...that type of withdrawal is unreal, i.e trainspotting?
anyways, GOOD LUCK BRO
