I have an idea. Why not try to drink three or four at the house? You say you can handle one at the house but when you go out your drinking is uncontrollable.
When you're out you probably have 3-4 to begin with and that sets you off.
My guess would be that it takes more than one beer to triger the craving in your particular case, As soon as you hit two or three, it's anybodys guess as to what will happen.
This way, you can safely try your experiment at home in front of the ball game.
