Played 10/20 limit poker at the casino for 18 hours a few months ago. Took a half hour lunch break (comped) and about a dozen or so lavatory breaks, but that was just sprinting to and fro and almost knocking people over in the process. Felt like a zombie walking out of there lazy and tired and unfocused, but caught my 2nd wind when I arrived home and felt refreshed and not tired anymore. Weird.
