Back when I was in college, I used to subscribe to the theory that sleep was wasted life, and would push myself beyond all reasonable boundaries, even for a college student. I scoffed at friends who suggested that they "felt better and more awake" when getting 10 hours of sleep a night. Averaging about 4 (and that only because I'd crash every few days), I scoffed at them "loosing" 25% of each day (6 hours = difference in amount of sleep).

This was, as the moral of the story goes, was until I tried it myself. Now I get a good 7 on a regular basis, sometimes eight. I find myself sharper, and more able to think. I wake up at the same time even without an alarm, and I'm awake, as opposed to the bleary eyed 3 dwarf routine (Sleepy, Dopey, and Grumpy) that I used to be when my alarm went off. All in all, I feel better for it.

Of course, I still have the useful talent I picked up with my no-sleep years, the ability to fall asleep anywhere at anytime I want. I understand you pick up the same skill in the military from a few of my friends. Now, I consider this the real "saver of wasted time".

YMMV, but try sleep on a regular basis.
