What do you do when you can't sleep? Do you lie in bed and keep trying, or do you get up and do something else? Apparently staying in bed and trying to sleep can be counterproductive.

When I had insomnia caused by depression, I found that keeping my mind occupied with some difficult but boring task was a good help as keeping my mind off worrying real life thoughts. Examples included teaching myself to recite the alphabet backwards, fluently (and every time I made a mistake or hesitated, I had to go back to Z and start again), and changing the word BLACK to the word WHITE one letter at a time (each intermediate has to be a real word).

Hope something works for you.
