Don't try, just quit. You can't hesitate. It's awful, I know. The first month was the hardest, the second month was even harder. But it does get easier eventually. You really can't listen to the Nicotine Imp sitting on your shoulder though: all it tells are lies, lies, lies. "Just one more and that's it" is a delusion. Always keep in mind why you are quitting and focus on that.

You can do it, you have the willpower. You are stronger than tobacco.
