You want to know how I help myself fall asleep?
Pick a topic… Lets say… geology.
Go through the alphabet coming up with an adjective and a noun that has to do with your topic that starts with the letter you are on..
Example: Artistic amethyst, Brilliant boulder, and so on.
You will be asleep before you get to the last third of the alphabet. Counting sheep has never worked for me, but this little game is a neat variation that will knock you out.
