Welcome to the forum. There are lots of ways people have gotten and stayed sober. For me, AA is working. I haven't needed to take a drink since July 17, 2010, and I didn't think I could go two days! I generally only can make 1-2 AA meetings a week but the 12 steps have seemed to make sense for me and I have had a lot of help from a sponsor. Others have had great success with substance abuse therapists and this forum.
The early days of sobriety can be tough, and detox can be medically dangerous, so you might want to see a Dr. and tell him/her about your drinking and decision to stop.
Welcome, and congrats on making a good step in the right direction!
