I was diagnosed with severe sleep apnea in December 2015. During the next several months, I suffered from ongoing sleep deprivation due to the apnea. I had to take sleeping pills and was suffering from anxiety from the severe sleeping problems. During this time, I did 5 overnight sleeping studies. From these, it was found that none of the breathing devices worked (CPAP, etc). Finally, the dental appliance, used during a study, reduced the apnea to mild levels. At this point, I was fitted for a Somnomed Fusion dental appliance. I have worn it every night for the last few months. I have stopped taking the sleeping pills and have consistently been sleeping well while wearing the device. It's a miracle!
