That's what I suspected YY - can you talk to Manitas about it, I'm sure he has the same.
Happy to, Liz... can't tell you *what* a difference my "gadget" makes; I *strongly* encourage anyone who might have sleep apnoea to get it checked out ASAP. Unfortunately, I do look like a cross between a fighter pilot & an elephant when I'm wearing it (it's SO romantic... NOT!) -- but it's definitely worth it.
One thing *you* can do though -- next time his snoring is keeping you awake anyway ;-) -- listen closely; does he stop breathing for a few moments & then start again? (My husband says he used to lie next to me in bed thinking "Breathe, damnit!") If so, the sooner he sees someone about it, the better (there can be a *long* wait for treatment). Not to mention that if he does any driving, there are *extremely* high risks involved in driving while seriously sleep-deprived.
Here's a link to a Radio 4 programme on sleep disorders that helped me (well, my husband, actually) finally figure out why my memory was so bad & I was tired *all* the time. (To hear the programme, click on the Listen Again link -- 2nd column from the left.)
Sorry for the thread-creep, but I thought other people *might* find it useful as well...
