What is your longest session playing live?

Was just wondering, actually, i wanted to see if I am a lunatic.

Played at Borgata once, sat down at a table at about 10AM saturday, left at about 2AM Sunday, 16 straigth hours.

I didn't event eat anything, just ordered coffee and water which increased the bathroom breaks, also took cigarette breaks.

I figure i dont get too many chances to play live since AC is over 2 hours aways, wanted to take full advantage.
