Watch out for the "Gee...I wonder what it would be like to smoke one now" thing. That's what made me fail so many times. My mom quit, and told me she was viewing it as an alcoholic who knew they could never, never, never have a drink because the addiction would take hold and they would just go back to drinking again. I'm not the slightest bit tempted these days.

"The Dream"--I think a lot of quitters have that. The first time I quit, I did it a few weeks after my mom quit (because she was having heart problems that led to a bypass days later). My mom called me a couple months later, and started with, "I had the weirdest dream..." and I told her what it was. You're just doing the usual stuff in the dream, take a drag, and realize, "OH SHIT, OH DAMN, I AM SMOKING AND I'M NOT SUPPOSED TO BE SMOKING BECAUSE I QUIT AND NOW I'VE RUINED EVERYTHING..." and you wake up and realize it was a dream. I only had it once though, in all the times I quit. Once was enough.

Congratulations, and good luck.
