I have mild apnea. The big concern was my low oxygen scores. Oxygen is part of every functioning organ of the body being healthy. I have never been wedded to living long -- just living healthy. I have two personal friends who are avid users of their CPAP machines because they have made a difference in their perceived health. Plus a neighbor and friend of mine in SLC (had an MD and a PHD) was into sleep research at the University of Utah. He was not motivated by money or he wouldn't have been in my hood. My sleep doc has used his for 25 years. I think the popularity is low on using these as it is such a process to accustom oneself to the use. My next step is an overnight oxymeter. And, honestly, I don't know if it is the CPAP or returning to regular exercise is the answer, but through this whole process, I am improving. My fuzzy headedness has diminished though I am still more tired than I should be, but maybe age is finally catching up with me. As I stated above I enjoy my sleep and was good at it. Wearing this device has been disruptive, but I think I'm a believer.
