Not that I’ve found. I have been assured by my partner that I am quite melodious by moonlight. Although my partner did not word it in quite that way.
There are nose strips made by Breathe Right and others that did not help me. Breathe Right and others also make a throat spray that’s been sporadicaly effective for me.
Sleeping on one’s stomach is supposed to help in some cases. Not so in mine.
I’ve heard of couples who sew a tennis ball in the back of some pyjamas - acts just like an elbow only automatic. (To prevent sleeping on back, which leads to snoring).
The weight thing might be an issue too. I went on a trip for a programming contest once - an older grad-student helping on the trip shared our room. Not only did his weight exacerbate the snoring, but even my strongest punch was easily absorbed by his girth!
I snore. NoCoolSpouseName would be very happy for a very long time if I did not. I’m not at all heavy. I too would love to hear if there are options, medical, home-remedy or whatever.
