There is only so much you can do to reduce snoring.
Unless you don’t have sleep apnea you can improve your sleep by having an appropriate night routine - no screens before bedtime or TV. Nutrition is extremely important, what you eat at dinner makes a huge difference on your sleep quality
with all due respect to doctors, they always want to solve everything with treatments and stuff like that. Granted sometimes you need that when you have something chronic, but I found that with the right nutrition you can improve you health drastically. We all know nutrition is important but the majority of the times is overlooked. I used to snore at night, but all went away with the right nutrition
Every case is different, talk to your doctor but also I would recommend to read and do your research and look at your nutrition habits
