Did not mean to be curt but was in a hurry out the door at the time.
I have direct experience with snoring vs. weight. When I got married I was about 175. When my weight went over 190 I started snoring. When I went over 200 consistently - alternate sleeping arrangements were frequent. When I hit 230 it got really bad. I have struggled with weight for a long time now, up and down. Every time I get below 190 my snoring pretty much goes away. The problem is a 'fatty uvula'. My doc told me the snoring would get better if I lost weight. He was right. He also told me that the uvula can be trimmed via laser. But if your weight stays up the problem could return. About 15 years ago the laser trimming was like $2-3K.
