There are also silicone devices which keep your tongue out of your airway by keeping it pulled outside. Studies show they work almost as well as a machine yet are much less likely to be rejected by users as opposed to a CPAP.

I tried this as well as a jaw-advancing device and I still snored like hell. The only thing that worked was the Zyppah (jaw-advancer + tongue stabilizer at the same time) but that made my jaw so sore and also triggered my gag reflex most of the time.

Eventually the snoring simply stopped. Not sure what caused it, but I'm happy.

These work decently but can really mess up your teeth by causing you to develop an open bite.

I'm seeing a jaw specialist right now to see if we can reduce the overbite I've developed from sleeping with a mandibular advancement device nightly for six years.

The jaw thing worked fine for me. Minimally intrusive. OTOH the CPAP was intolerable.
