Its sickening to even imagine sleeping in he middle of big tournies like sunday mil or storm , but sadly it happens to a lot of us , Just the other day i was playing the big 11 with a good stack size played or almost 2-3 hrs next thing i know im waking up & its morning & have been busted out with out even  cashing , i was so angry that i actually started laughing . Since most of the tourneis are played at night time im pretty sure im not the only victim of this thing called sleep. but its safe to say i ve learned my lesson & i put my alarm to ring every 30mins just to be sure, but again my solution has its perks now my roommate keeps complaing he hears alarm evry 30mins ooooooooops , lol
