Trig congrats on your day 2. It was the toughest for me. I am 6 days in now. Still edgy with my family and coworkers. I just found this site today and I think you did too. One day at a time we can beat this Nic Bitch.
Some good chatter going on in here. Just know that these cravings only last about 3 minutes on average. Granted, in these early stages they are more frequent, but that will dissipate. Trust me on that. So, when that crave hits, remember, you only have to leg it out for a few minutes before it passes. When it comes on, you go to your ammo - food, seeds, gum, water, push-ups, KTC, quit brothers, whatever it takes. Just don't pussy out in those few minutes. At the same time, savor those moments of pain. Say to yourself, "ahhhh this feels fuckin' awesome! bring it you nicotine bitch" ...whatever. Point is, embrace the suck and promise never to put yourself through this again.
