Yeah, meetings are nothing to be afraid of (even though most people are, before they've been to one and see what they are really like). Here's a link I like to share about
What to Expect at Your First AA Meeting. It's a very accurate description, in my estimation.
You absolutely do NOT have to say anything, although as mentioned in the article, it might make it less scary if you at least say your name. Identifying yourself as an alcoholic absolutely is NOT a requirement. I know people who say "I think I drink too much" or "I'm worried about my drinking." Or don't say anything but your first name. Nobody will laugh or disapprove. Every one of us remembers how nervous we were at that first meeting. After going to one or two you will wonder why it seemed like such a big deal.
