In my case I heard about Xylitol. Its a 5 carbon artificial sweetener that microbes will eat, but starve on. There are studies showing it can greatly help dental and sinus health. I tried the Xlear sinus spray to see what would happen and the quality of my sleep improved dramatically.
BIG WARNING HERE: equating snoring to sleep apnea is NOT the same thing. Sleep apnea can happen when snoring, but it is only 1 kind of type of snoring.
If you have nightmares and wake up in fits suddenly, it may be sleep apnea and you need to see a doctor and get a sleep study.
If someone knows you snore but you don't, you might be a mouth or nose snorer and a sleep study won't help. Each of those has a different set of solutions that don't overlap and something like Xylitol may not work for you.
