Invasion of the sleep snatcher

I've not had a wink of sleep all night. My cousin, Wayne, who is living with me at the moment, snores like a wildbeest with a raging sinus infection. The noise is utterly horrid, and can be heard all over the flat. I've screamed at him, thumped him, thrown slippers and cushions at him, and the dog has barked at some of his loudest snorts. But the snorting beast remains sound asleep, whilst shaking my home to its foundations.

I might insist on strapping a bandage around his head every night from now on, passing it under his chin to keep his mouth shut. He's the type of snorer who hangs his mouth open all night and honks away relentlessly. I even considered stuffing his mouth with a big wad of toilet paper, until I realised it was a choking a hazard. I'm going to insist he talks to a doctor about it. It really is too much. You know someone has a bad snoring problem when even the dog objects to their racket. Help!
