I conducted a similar experiement with similar results. Have a couple of beers and be home by 6. Got home at 6 alright, just four days later.
Ok, so I have got the "phenomenon of craving" that occurs with alcoholics and not other drinkers. I now know what the problem is, the research phase is over.
The next thing to look for is a permanent solution. I can never drink safely again, so how am I going to accomplish that. Will I do the alcoholic thing and try and figure out something on my own, or will I swallow my pride and go some place where the road to recovery is well trodden and sign posted.
The ability to learn from someone elses mistakes does not come easy to the alcoholic.
