Something underestimated until you don't get enough of it.

sleep 

You have been awake for 18 hours and are now viewing this useless definition of sleep. You are very tired and your brain is not functioning at its normal capacity. The bags under your eyes are starting to weigh you down. It's 1:30am and you have to get up at 6:30am for work. Another coffee wont help you now...

Turn off your computer and get some sleep you net junky!!

A drug that everyone can't resist taking.

sleep 

what you do when you are too depressed to face the world.

when the love of your life has been gone for the last five months, sleep is what you do to cope.
