I strongly recommend this anti-snoring prostheses for men who like me took a little weight, the size of the tongue and mouth increased airway in the throat during sleep. Just follow the advice written on the instructions for implementing the use of the prosthesis. The product allows to start his mark as oral comfort has not been reached. I once again after 5 nights because in the long I had a blister translucent paste that rested on my gum and it started to hurt in the middle of night. My wife can not believe the efficiency because the first night with the device in the mouth was miraculous! She has not suffered any snoring and I have to sleep a deep sleep apnea because my breathing stopped rot me sleep! A wake least tired morning is the first satisfaction and not the least because I no longer sleep in the day. This prosthesis has no odor contrary to what I read in the testimonials! I have a big mouth and frankly the prosthesis in place before my sleep does not bother me in any way. I keep the mouth moist all night. In the morning I take it off without any particular difficulty and cleans it with my usual toothpaste. Jaw muscles are sensitive to clock gene but disappears after breakfast generally. I STRONGLY ADVISES THE for effective action against snoring because I tried everything on the market and nothing gave result as relevant and sustainable!
