My guess is that at 10 days you are near the end of the worst of the withdrawals.
You don’t need to know a thing about AA to attend a meeting. All you need is a desire not to drink. I would encourage you to go. Lots of folks at those meetings who drank like you did. Just say its your first meeting and people will understand what’s going on with you.
Look back in this forum for threads like “my first AA meeting” to get an idea about the experience others have had with it. When you go I suggest you keep an open mind. No need to say anything if you choose not to.
I have a feeling you are going to feel better physically fairly soon, but staying sober will be a lot easier with the assistance of those who have been there before you. My advice is to learn from the many mistakes of others. Best wishes.
