I've been so drunk that when I woke up in the morning I had no recollection of how I got home. That's scary, because I know that I drove home, but as far as stoplights, I could have very well ran right through a red light. No memory of what route I took or whatever. I promised myself the last time I pulled an ass-move like that again, that I would NEVER EVER do it again. And I haven't. That was seven years or so ago.
I only drink at home now.
