Great choice, Wolf. Everyone knows how to quit...just spit the shit out. But this site offers a proven method to stay quit. It is called posting roll. If you really want to quit and you can keep your word, it will work for you.
When you post roll, you are promising that no matter what comes your way today, you will not use nicotine. Then keep your promise all day. Go to bed. Wake up. Do it again.
Take it one day at a time...you can't change the past and nobody knows the future. So don't think about them. Just focus on staying quit today. Also, plan now what you will do when the craves get really bad...like reading the Kern Family story. (That was especially effective for me).
Fight craves with exercise, seeds or the fake stuff. And stay glued to this site. The more you learn about quitting and addiction, the more you participate in this site by encouraging others or whatever, the stronger your quit will be.
