Yeah, it's happened to me once or twice... But I used to drink to the point of vomiting a lot more often..
It's weird, some of my friends blacked out every weekend when we were in college, but I never did until about 6 months ago. I usually get the spins and end up puking before I get to blackout stage.
My theory is that you have to 1) eat a lot of food, and 2) drink at a medium pace, consistently, all night. Hard alcohol makes it quicker, since it's easier to drink a lot of liquor and not even realize it until it gets on top of you.
I've never forgotten an entire evening, but I have forgotten a few hours...
LOL apparently one evening I came home from the bars and my friend walked in to my room and found me sitting in front of the computer, tearing SATA cables out. He was like "DUDE! WTF ARE YOU DOING", and I looked at him with wide eyes and proceeded to babble some inane gibberish, then announce that he was an asshole and that I was going to sleep. I didn't, I ended up getting the spins and vomiting... but I have only the very slightest memory of the entire event... My computer was pretty screwed up the next day... I managed to break 2 SATA cables. Fail.
I no longer allow myself to work on my computer when I'm that wasted....
