Was at an overnight company management retreat last week and had to share a room with a larger fellow. I woke up in the middle of the night to what I thought was my roommate being strangled to death. That's literally what it sounded like. Scared the crap outta me. Once I realized what was happening, I was tempted to try to wake him, but wasn't sure how he'd react (I don't know the guy all that well) or how serious the situation really was. But he sounded like he was dying.
I asked him about it the next morning, and he said something to the effect of "yeah I've got pretty severe apnea, but I refuse to wear one of them space helmets every time I sleep. When it's my time to go it'll just happen."
Well that's one way to deal with the problem, I guess, but I'd rather not be in the same room with him when the Reaper comes.
On a side note, over the course of the evening I watched the man put away most of a bottle of tequila by himself and a large number of beers, which I imagine contributed to the horrific sounds I was hearing more than a little. I'm talking Andre the Giant levels of drinking. After a mere 4 hours of sleep he got up to go deer hunting as chipper and awake as anyone I've ever seen. Claims to have never gotten a hangover, or even a headache, in his entire life.
