well, it's been all of 3 hours.
I've caught myself 3 or 4 times walking toward the front door to go outside and have a cigarette. Luckily, I don't have any, so to actually do that would require going all the way to the store. It's strange, I've gone a few days, even a week without smoking, no patch, no gum, nothing...and had no problems, because I knew that at the end of that time, I could grab a pack and light up. I've never really had those serious cravings of "I need a cig right now!"... until now.... :)
