For a gamer, racing and fighting games are great as they are easy to pick up and play a couple of quick games, require a lot of attention and smoking is impossible while playing.
I'm Trying to quit right now and I just take it reeeal slow. Never worked out for me if I quit spontaneously. Right now 3 cigs is my max (down from 10 last year). Maybe I get to quit next year. Good luck (to us both) :)
