Anecdote warning: I've already been wearing a mouth guard when sleeping for years due to bruxism. It's perfect for that. A couple months ago though when I was ~15 pounds heavier than I am now, I started to wake up struggling to breathe a couple times per week. Now that I lost the weight, it stopped completely. Mouth guard didn't help me there (or maybe it did and that it could have been much worse). It's probably better wearing that machine though.
