It was never your nose
You've tried the strips, the sprays, maybe the wedge pillows, the mouth tape. Some of it worked for a night, then quit on you. Here's what nobody told you: snoring almost never starts in your nose. It starts in your throat.
The second you fall asleep, your jaw slides back, pulling your tongue with it until your throat narrows to a slit. Every breath forces through that gap, and the tissue flutters. That flutter is the snore. It's why you breathe fine all day but rattle the walls the moment you're asleep, and why every nose fix you bought did nothing. You were treating the one part of you that was never the problem.
The mouthpiece does one quiet thing. It holds your jaw a few millimeters forward while you sleep, just enough to pull everything off your throat and keep the airway open. Nothing left to vibrate. Not quieter. Silent. You dial it in a millimeter at a time until the snoring stops and your jaw still feels fine, then leave it there.
No mask. No machine. You pop it in at night, take it out in the morning. And you finally get what you've been chasing for years: waking up rested, a silent room, and her back on her side of the bed instead of down the hall.
The whole fix is a few millimeters.
