New drug may replace sleep

A new drug looks promising for replacing sleep:

A nasal spray containing a naturally occurring brain hormone called orexin A reversed the effects of sleep deprivation in monkeys, allowing them to perform like well-rested monkeys on cognitive tests.

However, it's years away from being tested and approved for humans.  In the mean time, be sure to get plenty of sleep.  You'll feel better, keep the weight off easier and perform better.
