Step 1: Get tested for sleep apnea. If you have it, snoring is the least of your worries. Don’t skip this step.
Otherwise, sleep on your side, elevate your upper body (Amazon sells wedge pillows).
If you are certain you don’t have apnea, you can also try a chin strap. Just be sure any chin strap you buy pulls your chin up, not back, as this will A: Obstruct breathing, and B: cause major jaw pain.
What is the correct amount of usage? Why shouldn’t people use the languages they want to?
