Hi, I couldn’t sleep with the mask so I went to the nasal pillows. Those I could manage. For six months my scores were either 99 or 100. But I was feeling worse and worse. One morning I woke up and my mouth was dry and throat sore. I realized I slept with my mouth open.... so the 6 months were wasted. I got one of those straps to keep your mouth shut and in combination with modafinil, honestly, I have never felt better.
Just getting the strap was a 100% difference in my energy and my memory and my overall health.
