Been sober for three years now. Go to N.A. or A.A. meetings 6-7 nights a week. Have a sponsor. Work the steps. If you are an atheist, and are fairly open minded, you can still work this program with amazing results. The basic idea behind the higher power is that YOU are not it, meaning you have to give up trying to control things that are out of control and leave them up to fate/the universe. Most atheists can get behind this concept and there is lots of good info on the net about various ways you can work the program. I personally am a big fan of Albert Ellis/REBT therapy. I did REBT group therapy for three years before getting sober, and I have figured out ways to incorporate that into my tenth step.
The biggest thing is to make sobriety your main focus before anything else, and to just take it one day at a time. I figure any sober or clean day is a successful day. I just try to live each day sober, one day at a time. I don't drink, no matter what happens. Currently going through a break up and it makes it hard to not drink, but I make a commitment to not drink just for that day. Having a sponsor to talk to and the fellowship really makes it easier. Acceptance is key: not just of the fact that I can't drink, but of the fact that life won't always go my way. The "Serenity Prayer" is great for that.
If you have tried N.A. before and didn't like it, consider going back. Sometimes it takes getting used to. There are also some great programs out there like S.O.S. that are totally secular. Albert Ellis's book "When A.A. Doesn't Work For You" is great, as well as the "Smart Recovery" workbook. Smart Recovery doesn't have meetings anymore, I guess, but the textbook is still a classic.
Best of luck.
ps- If you happen to be a hardcore Christian, "Celebrate Recovery" is a good program that has been going on at churches lately. I know a lot of people who left A.A. for that, and they seem to do well.
