I quit cold turkey about 9 years ago. I was bitchier than usual for a week and as long as you realize is happening and why, it's easy to keep a handle on it. It's harder if you live in denial of you nicotine-craving bitchfest. Other than that, not many tips I can give you except don't even have one. Don't bum one from someone, don't have one after a few drinks, don't do it. I ate a shitload of carrot sticks too, just to satisfy the freaky mouth/hand interaction craving that your brain tricks you into. Good luck. You're making a good decision. Edit: I quit smoking, that is. I never chewed.
