Can't Sleep?

Here's an article in the National Catholic Register about not being able to sleep.  It recommends praying the Gradual Psalms.  Those are Psalms 120-134.  I might try it some time but usually,
when I wake in the night I don't want to put on a light to read.  I'll watch TV. 

What I thought was funny was the monk who walked with a lantern (must be a flashlight, nowadays) to see if any monks had fallen asleep.  If he caught a monk sleeping, then the sleeper had to walk with the lantern.
