Hi everyone, basically I am suffering from severe apnea and I was diagnosed last year (39.6 AHI). I've been on a resmed s10 apap for almost a year now and I've never felt well, even using the machine and it says it's treating (usually AHI below 3 or 2) and no leaks either. Every day I wake up the same way, dark circles under my eyes, yawning all the time and brain fog. All the doctors I went to could say is: just use the machine! I recently saw a sleep specialist dentist. She ordered some x-rays and found that I would be a good candidate for MAD, even with severe apnea. She told me that my retracted jaw is probably the cause, as the tests show. I am 22 years old and thin, I have no other options and I need some restful sleep to get on with my life. What is your opinion on this?
