I second this. DH also used to snore and has also now been diagnosed with sleep apnea. Having a cpap machine has given both of us better sleep!
I haven't read the whole thread, but this has been a significant issue during our 40 year marriage. My husband snores fit to wake the dead. In hotels we've even had people knocking on the door or adjoining wall to get him to shut the fuck up.
It wasn't just the snoring, it was when he stopped breathing because of his throat constriction and I felt like I had to stay awake to nudge him to make him wake up and breathe again. Putting on weight in middle age made it worse.
Eventually got him to go have a sleep study and he was diagnosed with sleep apnea. Got a cpap machine, which made a huge difference.
For a short time.
The bloody thing slips off his nose in the night and shoots off a blast of air that whistles past my ear and in my face. It's like a Jumbo Jet in reverse thrust and a massive hissing noise. He has one that just covers his nose so he has to keep his mouth shut or the air just shoots out of his mouth. So he got a chin strap but that's not very efficient. So I still find myself having to nudge him awake to shut his mouth. I've even offered to sellotape up his mouth so it stays closed. Bless him he suggested duct tape might be more efficient. Think that was a joke though :( The machine itself makes a constant humming noise too.
So cpap has been a revelation for him (even though some air escapes, there's still enough to keep his throat open so he sleeps) but not really much help for me.
We try to book holiday places where we can have separate rooms, failing that, ALWAYS twin beds in a hotel room. Just being 3 feet away from the prevailing wind can make it more ignorable. Also listening to Audible on headphones shuts out the hissing if I can relax into it enough.
I have friends who cannot understand how I/we could possibly be happy sleeping apart. One friend in particular says she has never slept apart from her husband in 30 years and finds our situation all very sad. In fact, when she had a hip operation and was in pain, they were so loathe to be apart that he slept on the floor beside their bed so she wasn't alone (despite there being 2 available empty beds in their 4 bedroom home.) Another friend with a similarly (but less chronic) snoring husband tolerates it because to sleep apart feels to her like failing him, and it not being a normal state of affairs, I mean, what would the neighbours think!? Do they think we have a shit marriage?
I've got past all that and so has dh. The secret to coping with the ups and downs of life is getting enough restful sleep. However you manage to do that is different for everyone. Not sleeping in the same bed does not mean that you don't have sex. It doesn't mean you don't love each other. It doesn't mean you've grown apart. It's simply the sensible answer for non compatible sleepers.
