I have had Sleep RX mouth guard for 2 weeks and have noticed I have been getting a good nights sleep. My wife has noticed my snoring has been reduced significantly. I have not woken up with a headache or have had to hit the snooze bar several times prior to getting out of bed. I prefer sleeping on my side and occasionally the mouth guard does fall out. My only suggestion is making the breathing hole a little bigger. I have had a stuffed up nose due to a recent cold and could use a little more air flow, it may be the reason the guard has fallen out.
