I am currently one day off of nicotine and hope this is the last time ever.
There are two components to nicotine addiction: physical and mental. Breaking your physical addiction is as simple as not using nicotine; there are withdrawal symptoms but it's not the white-knuckle straight jacket nightmare so many make it out to be.
Breaking your mental addiction is as simple as getting your mind in the right place. Understand that nicotine has power over you because you allow it. You give power to your addiction when you say things like "I hope this is the last time". Take the power back.
You have to get your head right to beat this bitch. It's simple, but it's hard. Take it One Day At A Time.
Day X: I will not use tobacco today.
Fight the urges, win the head games, keep your promise. Rely on KTC to help you.
Repeat.
And to all of you that are still "only" in your first five, ten days or so: your comments and help to brand spankin new quitters are just as important as some of the ol' ktc legends. Even more so, in fact, so be proud of your quit. Don't be shy; talk about what is working for you, where you're struggling, and pick somebody up today.
