I think you started your recovery process when you admitted to yourself that you had to stop drinking cause it was making your life unmanageable. That's the first step in AA. Admitting you are powerless over alcohol. (And the third day sober much of the physical symptoms of withdrawal are gone.)
I would suggest reading everything you can about addiction. THere are some stickiies in the Alcoholism forum that have parts of books so you can decide if you want to read the whole book. But getting knowledge about addiction can help you recover.
AA and NA are good for face to face support. (there are also other groups that help you stay sober.) I wish you well on your first meeting this weekend. I hope you get a lot of good from it.
