I snore loudly so I did the sleep test. Didn't have apnea, but it was found that I have an abnormally long uvula. It touches the back of my tongue! If I want to stop snoring I need to have it cut back, which costs $2-3000 and is considered cosmetic and not covered by insurance.
Got a grin and a blush out of my girlfriend when I told her "The doctor says I have an abnormally long uvula."
If you snore, get the sleep study. Several people I know have apnea and say the machines work wonders.
