Sleeping in side ways may be a good idea. It can be more, if sleeps on their back. One have to avoid having drinks atleast before sleeping, if any.
I used to snore so badly I would wake myself up and then had to have my tonsils out; that cured it for a couple of years.
I have started again now but not as bad and remember seeing an artical about laser treatment to the back of the throat to tighten up the skin - I wonder if it was the same effect ?
many people would pay twice to have this advantage - i can fully understand your decision 
anyway, i have some friends who had surgery for snoring, but some of them was still snoring after the surgery so i dont know if it’s worth it haha
so, what’s left? i say don’t sleep and drink!!!
my wife is “worse”. i can clearly hear her snoring and i want to change the damn channel, but she gets a better grip on the remote and mumbles: “i’m not asleep”.
Very Interesting and informative discussion for me. Before reading this topic i have no idea about my own self now i am curious to know if i am snoring or not when i am in deep sleep.
