Maybe you should stop attempting to rationalise the effects the alcohol had by retelling the amount of it there was, and accept you have issues with alcohol, and your inability to handle personal consumption.
Then start to take steps to deal with your issues.
Sobriety might be a good idea if you are incapable of stopping yourself at a set stage or point.
There are centres and lots of information and help available for you.
Good luck with more sucessful drinking in the future, and try not to kill yourself with idiocy.
