I have to chime in here. My partner snores, and I mean SNORES! It is awful but he cant help it. We have tried numerous devices, from mouthpieces to accupressure rings, nasal sprays, throat sprays, things that shut your nostrils, he's had laser ablations on the back of his throat, everything bar very extreme surgeries (that may or may not work...so no I'm not putting him under the knife with no guarantees!).. you name it, we've tried it. He is not overweight at all, and only a small to moderate drinker. We sleep in separate bedrooms because of the problem and still I hear him - a jet engine would be quieter. I fear going on holidays with him because we have to share a room.
I have expensive custom fitted airplugs (which are great) but I'm still looking for solutions. My latest is hypnosis for me (not working) and listening to really soothing music when I start to hear him... helpful but having to put on headphones is a pain. I've just ordered a new headband thing that has speakers embedded in them and doubles as an eye mask. Will be interesting to see if that helps once I load the right music to drown him out.
Anyway my point that I'm making is that really those that snore just cant help it, but I feel everyone's pain. Often snorers dont snore through the whole night, I would be inclined to ask a FA to wake someone if they had been snoring for more than an hour.... tricky situation but the FA who talked to marklyon clearly handled it beautifully. Love helps me to endure, but I do feel sorry for anyone else that doesnt feel the love.
