I've been taking a B1 (thiamine) suplement before bed and it significantly reduces reports of snoring and apnea from my sleeping partner. I think my apnea is more central than obstructive though. My observations are that I'm more likely to breathe through my nose when sleeping after taking B1, and that my nasal passages seem clearer, but I don't notice anything else (other than vitamin shop smell in urine). A neighbor suggested B1, and while I couldn't find any quality research, it falls into my bucket of 'if it's not obviously harmful... If it's stupid and it works, it's not stupid' and a bottle of b1 supplements is inexpensive. You'll know after a couple nights if it's helpful for you. I had a palette expander when I was young for orthodonic reasons. Fun times.
