Failing at recovery

You sound very knowledgeable about the options to achieve sobriety and stated frustration about staying clean and getting your life to where you want it to be.  Without knowing anything about you, it is difficult to address why, after so many attempts at recovery (rehab, AA, detox), you repeatedly pick up.  I wonder how strong and dependable your support system is and whether you have people available around you to use to prevent you from drinking and support talking through your feelings and pain.  You've mentioned AA and rehab - I would recommend you see a psychotherapist who can help you work through the feelings that trigger you to start drinking again.  Working through your emotional issues will help you with the knowledge and tools to accomplish ongoing sobriety and having the life you want.
