If you want to quit drinking then you should start with the 12 step program of AA.  This is not the right answer for everyone but it should be a starting point for most people because the level of support is very high with AA.  In addition to this, the solution is very widespread with AA meetings appearing in every major city and country in the world. 

If you suffer from alcohol addiction then you owe it to yourself to try and make a change.  This requires action; it doesn’t happen by itself.  So give AA a try and see if it works for you.
