I'm not surprised. There's an awful lot of you (in a good way) for alcohol to dilute into. Out of curiosity, how much does it take to drop you under the table?
I'm not sure, to be honest. Depends on how fast I'm drinking and what I do when I reach my limit. Last time I went under, I had consumed two six-packs, half a bottle of aquavit and a couple of shots of rum or vodka or something. But I drank the beer over the course of the evening and the spirits during the last two hours of the party.
That was the last time I drank myself into unconsciousness. Have not done it since and have no intention of doing it again.
