Gotta go with "Just a guy's" reasoning - drunken & s#$@-faced doesn't equal sleepwalking - he shouldn't be excused. I used to sleepwalk as a kid and it's God's truth that no memory exists for it, bizarre as it sounds. Used to scare the hell out of my mother when she discovered me wandering about the house and spied me wanting to pee on the lawn etc. But sleepwalking in kids isn't abnormal. They outgrow it. In Adults it is definitely pathologic or induced by sleep aids. Drunkeness is not an excuse.
