Go into the highly technical section, and demand someone explains to you exactly how AMD strain silicon. And then also, the architecture of the 45nm chip, and then, see if you can count how many 45nm chips it would take, side by side, to draw the word sleep in 36point font.
Depending on your situation (job...school....unemployed.....on holiday/vacation) you could just try staying up one entire night, like, missing out one nights sleep. Should get you niiiice and tired, ready to collapse into bed at like 9 the next night. You didn't say it had to be healthy.
Strictly on topic, I don't know any over the counter drugs that can help you sleep, however I'm confident that the chemist/pharmicist/clerk who may work behind the counter would be happy o point you in the right direction if you asked them.
