Dude, 4 weeks into my fourth time quitting, I hear ya. I smoked for a decade and after my first season of racing this year I saw quite clearly what smoking had done to me. **** that ****, I want to ride my bike as fast as possible.

Edit: I don't know about you, but cigarettes are ridiculously expensive in Canada now. I used to smoke about a small pack/day. That would run me $65 or so per week and over three grand per year. How much bike swag would that buy you? It's buying me a new 29er and a new cyclocross bike in 2008 - I can't wait.
