Hi Johnster and welcome to SR!
Personally, I haven't had the money to go to a treatment center. So, I tried AA.
I wound up in the hospital with alcohol poisening and on a ventilator. When I got out of the hospital a few days later (luckily no withdrawals) I went to an AA meeting.
I haven't missed a meeting yet (I'm going for 90 meetings in 90 days). I make my 90 in 90 on the 19th of this month and plan to continue daily meetings. That's what it takes to keep this alcoholic sober.
Music suggested reading the Big Book cover to cover... now THAT'S a good idea. Some of the first 164 pages can be a bit dry and the writing is "outdated" (I had no prob because I have read alot from that time) because it was written in 1939, but its is well worth it. And the stories following it will make you feel less lonely. They show how much alike we all are.
Try a meeting out and see what it's like. Try a few meetings out and see what they're like. And good luck to you!
