Whelp, my doctor definitely looked at my data and knew about me tweaking settings

Just saying it happens. He asked why I did it, because what they gave me was a prescription. I told him the initial settings weren't comfortable, and he said, "You could have called. We could make changes remotely" Then he asked why I tried APAP for a couple nights. I told him curiosity, to see if anything would happen to make the pressure go up. (I most definitely didn't say people on an internet forum suggested it.)

Nothing bad happened. It was the most gentle of scoldings. But it seems some doctors do check and question. I actually feel pretty good about that.

[EDIT] We are both happy with the settings I'm now using. He updated my prescription in their system. Truly, nothing bad happened.
