Just wanted to post an update, as my last thread was pretty desperate. I went up to Beth-Israel in Boston to see a sleep specialist there, and he knew right away that whatever I was told by my doctor here was incorrect and, in fact, was clearly not appropriate for my case. The CPAP at the pressure I was prescribed is way too high, and we have to find the real source of the problem before using such a device. So...he's referring me to someone he knows here near where I live who is top-notch (trained at Beth-Israel) and will do another sleep study on me that is multi-pronged and much more thorough. Might end up with the CPAP at a much lower pressure, or maybe investigate Inspire...we'll see.
So -- I'm off the CPAP for now and much more relaxed than I have been since starting it and being made aware of my nightly AHI (it just made me super-anxious!). My new sleep study isn't until May (at the earliest), though I'm pushing to have the Boston doc call down here and throw his weight around a bit. We'll see. In the meantime, thank you all for your responses and advice over the last month or so. Having a community of people who are in the same boat is so crucial!! Many thanks.
