Why are you still drinking? You've had DUIs. You are an alcoholic. The best way to change, I believe, is to give up drinking completely. If you aren't in AA you should be. You will never get through DBing and DRing by abusing substances of any kind. It is hard enough to be consistent when sober, let alone drunk or high.
If you aren't willing to stop drinking, I don't think you have much chance of success. Sorry to be so blunt.
