The Humility of Insomnia

When people complained to me that they couldn't sleep, I said, "So, read a book or bake bread." Until the last couple of years when I began to experience occasional sleepless nights myself, I never realized how useless you are without sleep. You're just too tired to concentrate, but when you lie down in your bed, energy goes through you like fire ants. Anyone have any cures that are non-pharmaceutical?
