Not for nothing is sleep deprivation used as a torture device. And as someone said previously, unlike with babies and toddlers, there is NO light at the end of the tunnel unless the snorer does ALL they can to reduce or stop it (and accepts that if they can't be totally cured, their "bruised pride" at separate rooms HAS to take 2nd place to the absolute NECESSITY of a regular good night's sleep for their partner) or, you separate.
When someone refuses to face up to the issue properly, it IS like saying that you don't matter .... that your health doesn't matter. Continual - over years and years - disturbed sleep totally affects your day to day life - your energy levels, your patience, your ability to get involved (or not) with all sorts of social activities (because you feel exhauted and washed out), your concentration AND, I am also convinced relentless tiredness affects your physical health and your ability to cope with any problems because you're so run down.
My partner probably does have no idea how bad he is ..... though he has been told, not just by me, but by his kids, his mother, his friends and just about anyone else who's ever shared a room with him. Even recording 5 minutes of the noise doesn't really get through ..... so what ? it's 5 minutes, ..... you can't record 6 hours of it and play that back to them can you ? Nor can you replicate the sheer frustration, fury, nausea (because you feel so exhausted) and frustration experienced when lying next to a severe snorer for the umpteenth time in many years. I think part of my frustration is that my "complaint" is therefore trivialised and my concerns not taken seriously ...... like I am being mean, and/or exaggerating (but why the hell would I do that ?)
As Nooka said, this isn't white noise like background TV or even something like next door's lawnmower. Some of the snorts, hacks, gurgles, wheezes etc my partner makes turn my stomach .... imagine someone sounding like they're about to throw up or bring up a load of phlegm. Add to that the "traditional" snoring and he sounds like a tortured warthog (at best). There is no rhythm to it ..... it goes silent for a couple of minutes, you try to relax down into sleep, and then bam, there's a sudden outpouring of disgusting loud noise. The volume levels go up and down all the time too.
The thought of a) enduring this indefinitely and/or b) dealing with all the (pathetic and selfish IMO) "offence" caused by insisting on separate rooms permanently makes me terribly upset. In fact, if we go away and there isn't a spare room to fall back on, the prospect of disturbed sleep FOR CERTAIN and no escape, totally marrs the occasion before we've even started and my heart now sinks at the thought of going away. Conversely, if he's ever away on business I feel nothing except huge relief at finally getting some sleep.
All I can do is keep trying to get him to sort this out until every avenue has been exhausted, and then we can think about what to do next. But for me, if nothing's going to work, then he has to be realistic about sleeping separately (that doesn't mean no sex) because he can't expect me to survive on minimum sleep for the rest of my life ..... and if he can't/won't do that then I can't see any other way out of it other than to separate eventually.
I know I've gone off on a rant again - sorry - but this is SO not trivial and I totally understand what it's like to have a partner who doesn't even try properly to sort it out. It feels really contemptuous actually.
