Just to make sure nobody takes the above as facts and decides modafinil is what they need: basically everything in parent is incorrect, except that sleeping is good for you.
Modafinil does have various side effects, does not allow you to never sleep, and you do have some effects of sleep deprivation if you use it to skip nights. The shady sites that sell it do ship to non-US addresses. Your doctor probably also has it (provigil), if you have narcolepsy.
