Hi Ginger, Thank your so much for the explanation (your case). You help me understand what the doctor told me. I agree with you that 17 seconds is like eternity when you are not getting any air especially that it's not only once in a while but very often per night. I have 30 arousals per hour when I sleep. Yes, here we have national healthcare. But the system is worst than your Medicare. We have to wait from 6 months to 24 months to see a specialist. It takes about 2 weeks to see a GP. Then you have to wait about 6 months to have the tests and another 2-3 months to get the result. Then you wait again for the next test. There are not enough doctors and some people don't have any GP so when they are sick the only way to get treatment is to go to the ER. Many doctors don't take any new patients. I am lucky to have my own GP. The problem is that the government only trains a certain amount of doctors. They decide years ahead how many doctors they will need. They made the wrong forecasts for different reasons, ie the new generation of doctors don't want to work 80 hours per week (they like 9:00 to 5:00 or 2 days a week), etc., so that's why we don't have enough man-power doctors. We also have the cutback in the health system but that's only policital. More and more the government want private insurance to take over the health system so that's why we have to wait. They know that some of us have private insurance who will pay for the testing so if they make us wait long enough we will go privately. There are some tests that you cannot do privately, ie TTT because it has to be done in a hospital setting. I had to wait almost 1 year to get my first TTT and 18 months for another one. Thanks for sharing the sleeping tips and the chin strap tips. I am new to sleeping disorders and I want to learn as much as possible to be able to help myself improve my quality of life. I am glad that the CCAP machine is helping you. I can't wait to be given a chance to try one. In the meantime I will do all my best to improve my sleep. I find that I sleep better when I have 3 pillows and I am on my side. I can't fall asleep on my back. Sue "So if you do not have REM sleep they can not tell if you have sleep Apnea?" I don't know the answer Sue I just know that this is what the doctor told me. The specialist said that I slept so poorly that the study raised more questions than it gave them answers. That's why I need a repeat study. I know Ginger had some hypoapnea in the non-REM sleep but I don't know why the doctor told me that. I need to learn more about sleeping disorders. Ernie
