Sleep is like a drug. Take too much at a time and it makes you dopey. You lose time and opportunities.

There is plenty of time to sleep in the grave.

I've realized that most of my best ideas have followed a good night's sleep.

Six hours sleep for a man, seven for a woman and eight for a fool.

The serpent, the king, the tiger, the stinging wasp, the small child, the dog owned by other people, and the fool: these seven ought not to be awakened from sleep.

Who said nights were for sleep?
