hand long can I last in a live game?

[JMP300z]

On a good nights rest i finished off my last vegas trip with a 30 hour session. I wanted to play till my flight and couldnt fit in some sleep. Started at 2-5NL and moved to 10-20. Towards the end i was a bit delerious but it was definitely +EV. My best guess is somewhere around 48 hr session if you get real hopped up on diet cokes/coffee and hot chocolate.

A good player/friend tried to put a move on me at the 10-20. I raised UTG w/ KK, he 3 bet me in the BB, i 4 bet, he called, flop Axx, check check, turn pairs the middle card and puts 3 clubs on board, he bets, i raise, he 3 bets and i call him down on the turn and river to see 9 high.

"How did you call me down"-him
"Im too tired to consider folding kings"-me.

Good luck and dont listen to all these sissies that say the game will be there when you get back...how do they know for sure?
