I can only tell you what works for me and that is AA meetings, a sponsor and working the steps. Honestly I don't know what the stats are, but what I do know is that if you really want to stop drinking then it can be done.
Half measures avail us nothing, I am proof of that, today I do whatever is suggested to stay sober because I don't want to ever go back to where I was. I went to any lengths to get high and drunk and today I go to any lengths to stay sober.
Good luck with whatever you choose as a program of recovery.
