Hah, I have one to experiment on right now.
A good cuppa (mint or licorice spice, or anything with an aftertaste you enjoy the aroma of)
Cough drops
Sugary juices, and if it's hard to eat, salty soups
Guilt trip someone into serving you all day (helps you to forget it anyway)
Get lost in a good book
Gimme 5 good books to get lost in when you're sick
