So, I'm officially a person who's not sure how much he snores.
I used to be an absolutely terrible snorer. My ex-wife had to wear ear-plugs, and after sharing a hotel room with my parents once, they swore they'd never do it again because of my snoring. It was apparently atrocious.
Then, in November, I had my upper wisdom teeth removed. I was shocked to find that my sinuses were suddenly clearer than they'd been in at least a decade, maybe two. I also found that I was waking up more refreshed after getting the same amount of sleep. Suddenly 6 or 7 hours of sleep felt like 8 or 9 used to. Given those two things, I'm pretty much certain that I'm at least snoring less than I used to, but since I never used to hear it even at its worst, and I sleep alone now, I have no idea what my current level of snoring is. It could be nearly as bad as it was, or it could be relatively minor and occasional.
