Insomnia?
Just Go To Sleep
And Forget About It

"A technique that I have found most useful is to envision myself in some ideal spot: a house, say, that is perfectly secure and warm while a blizzard rages outside. I picture a window next to my bed, with snow striking against it. Then I work out the layout of the house, the heating system, the surroundings; and I make them all ideal so that the idea of security and no disturbing thoughts can intrude."- Edward
