A.A. meetings vary in format and size. There are discussion meetings, speaker meetings, meetings which center around reading A.A. literature, and some meetings are combinations of these formats.
At any A.A. meeting, alcoholics share from their own experience about what their lives were like when they were drinking, what actions they have taken to recover from active alcoholism, and what their lives are like today.
A.A. does not keep any membership records. You do not have to reveal anything about yourself when you attend a meeting. Attending an A.A. meeting does not obligate you to anything; you are welcome to make your own decision about whether to come back.
