Hi everyone, I've just been diagnosed with sleep apnea (something I had suspected for years). I received the diagnosis with a home sleep test and they prescribed an APAP machine with no in-office sleep study. I had about 64 episodes and my oxygen level dipped into the 70s (don't know the exact number as I was just told the results and didn't get a copy. They have the APAP range set from 8-16. I've used it for the past three nights since I received the machine (Resmed AirSense 10 AutoSet and P10 for Her Nasal Pillows) with the data below:

Here is my issue: I'm exhausted. I feel almost more tired than I did before. I have all the happy faces on the machine saying that everything went well but I'm more tired than usual. I know I'm not leaking through my mouth (at least not last night) and I haven't taken anything off. Everything else has stayed the same, so the only change is using the machine. Is the machine accurately recording these events? Any suggestions?
