Great choice, John. Thank your buddy for referring you here. The reason you failed in the past is that you were "trying" to quit. There is no trying. Trying is bullshit.
What you must do is DECIDE you are quit. It doesn't make a shit who says what, or what life throws your way. You are quit. And that is that. No excuses, no bullshit. You are in control now. You will always be an addict, but you can control your addiction.
Go to the Welcome Center link above and learn how and why we post roll. Quitting is done one day at a time...just focus on today...nothing else.
Nobody is asking you to quit forever here. Quitting forever is hard. So we don't do it. In fact, don't think about tomorrow, next week, next month, or whatever...just focus on today. We'll deal with them when they get here. YOU just need to sack up and decide that come Hell or high water, you WILL make it through today without nicotine. Anybody can make it one day, right?
Replacements - load up on mints, seed, fireballs, whatever. Drink tons of water and exercise. Fight urges by doing push-ups. YOU CAN DO THIS. Quit like your life depends on it...because it does.
You got this, brother!!! Post roll, read everything you can, and live free.
