My husband used to do the same thing. When he was in college at Virginia Military Institute, they could hear him from several rooms away!
About three years ago I finally talked him into going to the doctor who gave him a referral to a sleep clinic. He has sleep apnea. They gave him a CPAP machine and he's been sleeping like a baby ever since (and so have I!!). It's nice to be able to sleep (I mean really sleep) in the same room with a former freight train (I swear that's what it sounded like!!) :-)
