It was fine as long I was reading on my back. And the nasal mask portion itself was comfortable. But the headgear was like a hard cage sticking out around my face when I tried to lie on my side. I finally gave up and switched to the Nuance Pro I have as back up. Problem is, with the Nuance Pro I still wake up about a half dozen times (at least) per night. Also, I tend to swallow a lot of air, leading to stomach discomfort/bloating and burping and (really weird) my teeth hurt. I must clench particularly hard to keep my mouth closed. Both those "symptoms" had gotten much better with the soft cloth mask.

Booksfan, I agree with others that a larger pillow size on the P10 for Her will be ideal. I want to make some suggestions on settings and your Sleepyhead chart. Your chart is great, but you are getting very poor definition on the Flow Rate due to the scale being too large. You can right-click on the left margin of that chart where it says Flow Rate to make some changes. Right-click on Flow Rate and select Y-axis, and over-ride the scale. Set the minimum at -80 and the maximum at +80 and you will see useful definition in the wave form. Secondly, right-click again and select dotted lines and check the box next to Zero. That will give you a line at the zero flow where inhale and exhale intersect.
For settings, your minimum pressure is set to 5.0 cmH2O, but your median pressure through the night is 11.44, and the pressure never goes above 14. I think you need to increase the minimum pressure to 9.0 so you get a bit more consistency. The machine is doing a good job of stopping events, but your minimum pressure is just nowhere near what you apparently need. If you want to set a top limit for pressure the maximum would be 15.0.
Now let's talk about comfort. You are not using one of the most important comfort features that your machine offers, EPR: Exhale Pressure Relief. You can use EPR to reduce pressure from 1 to 3 cm during the exhale portion of the respiratory cycle, and most people find this very nice. Please feel free to experiment with an EPR setting that works for you. You may need to enter clinical settings (control knob + home button) and scroll down to Comfort settings and Select EPR. Select FULL TIME and choose a setting of 1, 2 or 3. You're going to like it. While in clinical settings you can also select ESSENTIALS and change from ON to PLUS. This will provide a more detailed on-screen sleep report.
