When I read Insomnia by King...it gave me insomnia.
I loved that book. Insomnia. One of his better ones, IMHO.
I went thru a Stephen King phase in college-early adulthood. Then he just started to disturb me too much. I never read Insomnia, Misery, etc. I literally had to move to a populated part of the house from my bedroom to finish "Pet Sematary". I later wound up with a cat that looked like that after she was hit by a car and lived.
