I do and I can tell a big difference from when I wear it from when I don't. Before I got tested I was falling asleep driving home from work. Then when I got home all I wanted to do was lay on the coutch and sleep. I went I had the test done. I don't see how anybody could sleep with all the leads and crap that's all hooked up to you. Well my test results said I stoped breathing 30-40 times a hour. Also during that time my Blood oxygen levels dropped below 60 percent. I have been useing one for 3 years now
