Roll call is the most important thing you can do here. By signing it, you have giving your daily promise to that group and the entire website that you will be nicotine free for that day......stay quit for 24 hours and repeat. Your word and integrity is about all you have here.
The men and women in your quit group are at the same point in their quits as you are, lean on these people, they will be your lifeline. Other than that, post roll early, everyday and get involved.
Congrats on your decision.
