Midnight Snack and my teeth?

Now i've often wondered about this, like most pointless questions in life: before bed, i brush my teeth like a "normal" person then call it a night. I might fall asleep for a few hours before waking up and realizing i've got the sleep-induced munchies..ooo what to do what to do!. Herein lies the dilemma... when i have the midnight snack, taking into consideration the havoc my choice would wreck on my teeth, is it better to indulge on something sweet or something meaty? ya i know I'm supposed to brush my teeth after meals but c'mon it 2am!!!
