I set in on some for a week because I used to treat so many that would drink too much. I remember the structure of them, serenity prayer--->Daily Affirmation----->(Volunteer) Would read from the Bluebook------->Those having issues would talk and the group using collective wisdom would reply. Younger members would have someone with longer sober time called a sponsor. They worked on something in the Bluebook called the ten steps, I never saw what those were. The sponsors would help their charges get through them and be available as an emergency measure if someone was thinking of taking a drink. I could see how they would be helpful to some, if you felt odd, then perhaps not so much for you. It seems long but it will pass in no time it is good to have the experience. Also if you ever feel as if people don't like you, it's a good place to go, because they all say, "Glad you're here."
