I'm going to kill my husband (not literally)

I don't sleep as well as him so I'm up much later than him at night. 
Every.Single.Night. He drives me absolutely nuts with his snoring. It's honestly the most obnoxious noise I've ever heard in my life. And he only does it when he's on his back. So everytime he snores, I have to nudge him and tell him to roll over. And he gets mad at me! Don't sleep on your damn back and I won't wake you up! 
Does anyone else's husband do this? 
I love him to death but geez louise it's aggravating sometimes!
