text: Not only has this product changed sleeping for my wife, (because she doesn't have to hear me snore) it changed sleeping for me. I noticed I am getting overall better sleep using this product. I may be a bit bias, because I am use to sleeping with a night guard, but having the product in my mouth at night was not a problem. If you have never slept with something in your mouth, it may take a while to get used to. It took me about 2 to 3 week to get used to my night guard. I promise you, if you can get use to keeping this in your mouth at night, it will make a positive change.
