Personal experience has taught me that you can actually put off sleep for hours, so long as you keep active. In a fight, where you are pushing yourself to stay awake and keep active plus the adrenaline rush, 'willpower' would be a lot more effective that you'd think. I find that it's when you stop that sleep hits you hard, as your body goes "well, I don't need to push anymore" and any semblances of energy it was dragging up disappear completely.
