Jumpin' on the Apnea bandwagon here!
Please just have him have a study done. DFIL (62 at the time)
suffered a massive stroke (the bleed, not blockage type) as a result of untreated OSA. He was a lifelong snorer as well as severly hypertensive. Now he is paralyzed on his left side, and our lives are forever changed. We had been trying to get him to have a study done, as DH has OSA, and it can be a genetic problem, (often compounded by excessive weight, alcohol consumption, and a host of other issues.)
DH uses a CPAP as well. I have to say, I hate it. As soon as it goes on, I feel like I lose a husband, if you take my meaning.

But the good news is, he comes back to me every morning, he is not grumpy or just "wiped out" anymore, and I feel like I saved his life. After trying every one of the previous suggestions on DH, I began looking at him while he slept. (yes, I did contemplate the struggle he'd put up if I tried the pillow over the face solution!

) It was then I noticed he stopped breathing. After about 6 months of prodding, he finally went and he was having 8-10 episodes an hour! His BP would go through the roof! The Dr. even said he was surprised we didn't have marital problems, his case was so severe. (this was an actual question on the intake survey)
Anyway, he is a success story, while DFIL is a casualty. Don't let a silly study keep you from ruling out a potentially life threatening condition. Oh yea! Not every one who snores has Apnea, and not everyone who has Apnea has to us a Machine. Depending on the severity, some lose weight and that fixes it up nicely. Good luck to you. Until you get the study done. Ear plugs worked best for me. The soft spongy kind that expand once they're in the ear canal.
