My brother has sleep apnea (and snored like a freight train - he literally woke a friend three hotel rooms down). His life changed dramatically when he got on CPAP a few years ago. It took him a little while to get used to it, but it works wonders.

I have two other friends who sleep with some sort of mask (not sure which variant), also with good results. One travels a lot, and never goes anywhere without it.
