Contrary to what Wulfman seems to believe, not everybody does better on fixed pressure and not everybody can live without flex or ramp.
Question: When you say you were up and down all night, does that mean that you got less sleep last night than you've gotten in previous nights?
Here's my first sincere suggestion: If you were able to get more sleep last night than you were getting when the machine was set to Auto, keep the current settings. But if you got (substantially) less sleep than you have gotten when using the machine in Auto, set it back to Auto.
I think a major part of your current problems are aggravated by changing too many variables way too frequently. It takes time for your body to adjust to the feel of having a mask on your face and the sensation of air being blown down your upper airway. And when you keep changing things around, that makes it even harder for your body to sort out what the new "new" is supposed to feel like.
So once you figure out whether switching to fixed pressure was a net gain or a net loss, set the machine's settings where you want them to be and leave them there for at least a week or two.
Next: The constant changing of masks is making it harder for you to learn how to sleep with a
particular mask on your face. I understand that you are fighting leaks and dislike the chinstap. But constantly swapping the mask around makes it even harder for you to figure out what kind of tweaks might be possible to make a
particular mask work better for you.
You write:
The most comfortable are the F&P Eson, F&P Pilairo (when it's not making my nose clammy and cold), and to a point the GoLife for men (when the straps are not digging into my cheek even with the headgear loose). The ones that are uncomfortable are the Full Face mask, Wisp, Nuance Pro, and a couple of FFM that I can't recall the names of.
If I were you, I'd pick either the FP Eson or the F&P Pilaro and try using them for at least a solid week---regardless of how bad the first couple of nights are.
My understanding is that the FP Eson is nasal cushion mask, which is a small nasal mask that covers the tip of your nose, but has a forehead support and a what looks to be a pretty substantial, but soft fabric headgear with a cushion that uses an "air seal" rather than a "gel" seal. The FP Pilario is a nasal pillows mask with a very minimal headgear. Figuring out how to make these two masks work requires using techniques that are quite different from each other.
Once you pick one of these two masks, you need to use it for at least 5-7 days in a row. You could start out by trying to use the mask without a chinstrap for a night or two. At this point, don't worry about any data except for
the leak line and
how long did you manage to sleep with the mask on each night. And I mean estimate the actual sleep time
with the mask. Don't count the time you wear it while watching tv in an effort to get used to the mask.
Analyze the leak line in the morning and also keep a log of how long you think you slept with the mask each night and what ever your impressions are about how rough the night was. For the leak data you want to see just how bad the leaks are on paper to try to determine whether there's a lot of mouth breathing going on. If you can't find the leaks that bugged you during the night in the data, you'll know the problem is small, but irritating leaks most likely around the edges of the mask.
Once you finally figure out how to make one particular mask work--in terms of being comfortable enough to sleep with and in taming the small, but irritating leaks around the seal, you may find that the problem of taking the mask off all the time will start to resolve itself. If not, then that's the next problem that you'll need to work hard to fix.
I just want to lay down to sleep, uninterrupted, for 8 hours. I have yet to do that.
It is extremely important to have
realistic expectations about CPAP. Until you manage to learn
how to sleep with the mask of your choice on your nose, there's going to be some sleep disruption. But eventually things usually do get better: Your brain eventually learns how to fix small leaks without waking all the way up. Your brain eventually learns to trust the mask enough to quickly get back to sleep when you wake up in the middle of the night for no particular reason.
