I too can be 10 shots hard liquor down, I'm talking mainlining one after another, and appear completely normal.
Which is typical as I have a (hopefully) past history of alcoholism. But I also have a documented drug resistance to intoxicants such as anaesthetics, narcotics, etc and a partial insensitivity to pain. So, I need more of it to have an effect and apparently that effect is less than normal for my weight range.
As for what effect upwards of 15 shots in quick succession has - it slows my mind down. Stops the constant, constant spinning, and just mellows me out into nothing.
Which I enjoy. Hence the alcoholism, and the abstinence.
