So this is what I would do and what I think.
My guess is that something is not letting you get comfortable. Now this may just be something you need to get used to, or it may be something to adjust. What I do is adjust everything I can to get the best sleep I can and then get used to it. Adjusting everything of course does not mean to adjust everything at the same time. Sometimes when I got one setting right and then changed something else, the first "good" setting needed to be changed again. These things tend to interact.
Make sure you know all the settings you can adjust and really focus on how you feel when you adjust them. What your feeling with CPAP tends to get mixed up with things that you felt before CPAP, like pressure before was an indication of nasal congestion, now pressure is a good thing.
Make little changes. If it's worse, try changing it the other direction.
It looks to be a good idea to up the starting pressure. If you have a problem starting at a higher pressure consider using the ramp feature so you don't get a big jump right at the start. I have always used ramp to ease into pressure. An average time to sleep onset is 22 minutes, keep that in mind for the ramp time.
How are you doing with the hose placement? do you have a hose hanger system? I found it very helpful to not get tangled up in the hose.
Don't assume that what you thought you liked before CPAP will be the same with CPAP. I thought I liked humidity like from a hot shower, with CPAP I have it set to off, at 63 degrees (F)
and even a full tank of water for passive is too much for me. A dry tank is not enough, so I fold a paper towel up and soak it, then place it in the dry tank. For me this is perfect.
Some people can fall asleep anywhere and under any conditions, for me I tend to be very sensitive to my sleeping conditions. I can sleep, but to sleep well takes some adjusting things.
Good luck and keep at it
