X, if you can't take Diesel's shit, you definitely aren't tough enough to quit. As he says, only you can answer that question. If you decide to make the daily commitment to do so, you've come to the right place. Here you'll find support, coaching and kicks in the ass to correct you when you go astray, not done because we're pricks (well, some of us are) but because we'll be investing in your quit and we all quit together here.
When you're ready, join the March quit group and log in for Roll. That is your promise to quit for the day. Make roll call everyday, and commit to quit each day, one day at a time.
