I have been trying all types of remedies and gadgets. This one actually works! I use a sleep app to record my snoring. I put in the mouthguard the first night. In the middle of the night, I took it out. The recording was proof! My snoring started heavy after I took out the mouthguard. On the second night, I was able to keep it in most of the night and the same results. Early morning recordings of loud snoring. My "Snore Card Score" kept going down the longer I kept the mouthguard in. I am going to buy some additional products to adjust the bite, now that I know more. I had to cut the backs of mine after fitting them because I have a bad gag reflex. After cutting it down an inch, I had no issue with gagging. It does take time to get used to it being in. I believe that getting another one and adjusting my bite (i didn't realize i have a slight overbite) will do the trick. I recommend this remedy highly!
