Lots of inebriation of several varieties catches up fast.
This isn't something I usually do, but this year I had reasons. That said....
I polished off half a large bottle of Manischewitz Sweet Red wine. At my body weight (I'm 6'1 and 220+) it didn't get me sloshed, but I had a serious buzz, and was able to remember it too!
I was laughing at just about everything and my wife said it was the best mood I'd been in all year (though I'm sure there were some
non-alcohol induced good times in 2010.)
Around 12;30 the buzz put me to sleep and next thing I knew it was 11:30 New Year's Day. Best sleep I had all year!
I'm quite short...5'3" and a fluctuating weight. I go between 115 and roughly 170. Right now I'm about 160. So, technically, not a LOT of alcohol is needed for me to be buzzed/drunk.
I drank not only enough for me, but for my buddy, my cousin, you and anyone else. On top of other things that'll go un-named. I had a WILD New years. Then went to work the next morning. How I managed to walk to work, I'll never know.
