Not that impressive, but I once had only 5h of sleep in a week.
Working at night as security guard, studying Electronics Engineering during day .
In another time, in my first time in the UK, I drank a can of Relentless energy drink and stayed 3 days without sleep. That could have been useful in the first fact...
Oh, just remembered. Once I fainted after getting 3 shots (paintball
) in my chest.
Had to be picked up in arms out the field.
