For the New York Times Opinionator topic All-Nighters (discussing all aspects of insomnia), New Yorker cartoonist Roz Chast provided some advice in the form of a comic. She gets to sleep by doing a simple A-Z game :
I try to list various things from A to Z: countries, rock groups, prescription drugs, movies, books, celebrities whose first and last names begin with the same letter… you get the idea. I don’t mind repeating categories from one night to another. Diseases might seem to be an unlikely insomnia game category, but for some reason, it’s one of my favorites.
