instead of outpatient program for alcohol abuse/addiction, have you considered FTF therapy with someone to discuss maybe the reasons why you wake up face down on the carpet/bushes/ floor at times. Approach the problems you are facing from another perspective.
I don't if there is such a thing as "reactive drinking", or the details of your last binge, but it seems they are getting stronger and more harmful....and it starts with one pint? (of beer)? You have resolve and reasoning ability. It wouldn't hurt to seek some help.
I've also exhibited self-destructive behavior and got help to recognize the signs of when and why I do really self-destructive things to myself....and I was able to stop (at least for now)
