How can I convince my wife not use the snooze on?

Ask her to try it your way for a couple of days...if she doesn't like it, or thinks she was getting better sleep her way, have her go back to the way she was doing it. Ask her as a personal favor to you...if she loves you, she'll try it. If she won't/can't, consider sleeping in another room. Not as a punishment...but you need your sleep too. I do it all the time. My husband snores like a chainsaw! I can't sleep. I have tried everything to stop it, but the only thing that works is sleeping separate from him.
