I have several close friends who are insomniacs. Over the years, I've heard their stories about being up in the middle of the night, completely awake. I see them yawn at 11 A.M. and know that, regardless of what they are doing, they'd probably rather be in bed sleeping. I've always had sympathy for them, but I've never really understood it.

Some struggle with medical issues - like insomnia - that make sleep hard. But for many of us, the quantity and quality of sleep come down to a matter of choice. Still, only a few enterprising economists have looked closely at this, and generally, those have assumed that we choose our hours of sleep optimally.

I start work at 5 in the morning and I have a wicked insomnia problem.

The best cure for insomnia is to get a lot of sleep.
