Blacked out twice that I remember. Once when I was 15 and left a party but don't remember the walk home. Apparently I got in a fight coz when I got home I was beat up pretty badly and was for some reason gripping someone else's tooth in my right hand.

About 10 years ago I was at friends house drinking. I don't remember leaving but I came out of it rounding a corner on my bike on the other side of town.
