Sleep apnea diagnosis and CPAP.

Losing weight and not drinking alcohol.

Pushing spouse from back onto side

Breathe Right strips worked for a bit but weren't effective long term. Eventually got tested for sleep apnea and ended up with a CPAP machine.

A sleep study would probably be a good idea just to make sure you’re not stopping breathing while snoring - AKA obstructive sleep apnea. A sleep doctor may even have some other ideas like custom dental appliance or things other commenters and I aren’t aware of.

CPAP worked for me, dental appliance did not, nasal strips never worked

An anti-snoring appliance made by my dentist. Works great. Wife gets upset when I don't use it.

adjustable bed to sleep at an incline, or if i'm on vacation in a hotel i make a T-shape out of the pillows to incline as best i can from the waist up. if my sinuses feel clogged at all before bed i might take a claritin or something. exercise to get rid of some body fat also seems to have helped.

got rid of my ex wife

Earplugs.

Sleeping on my side

Getting divorced. I haven’t had a complaint about my snoring since

What's your diet? What's your habits?

Overall improvement in diet and habits can have an amazing effect on this. Cut out all the unhealthy shit and start drinking water exclusively. You got this.

Getting tonsillitis and having my tonsils removed.

My snoring appears to be dust / hayfever related.

I wash my bedding regularly, vacuum my bedroom regularly, also under the bed, and have a shower before bed.

It appears to have reduced my snoring.

PS. CPAP didn't work for me, made things much worse.

Bipap works wonders for snoring. I fucking hate the thing though.

Others have had luck with removal of tonsils/adenoids but that can be really rough as an adult.
