Here is my data from last night.
 
I don't think It looks as good as the data from the night before.  As far as I can remember, that is the lowest patient triggered breath % I have ever had.  And the AHI of 6 is back almost where I was before changing the pressure support.  I am holding off on making any generalized assessment of that latest adjustment because, like I said, there are too many confounding variables at this time.
As to the other one-size-fits-all question--  How do I feel?  I feel short of breath, like I need to take a deeper breath, but even the deepest one I take feels too shallow, like my chest won't expand enough.  
Tree pollen count is very high today and moderate for grass.  Two of my neighbours are out doing yard work.  I have most of the windows closed to keep the pollen out, but as a result, it is stuffy in the house, like there isn't enough air in here.  
Also, we are finally having summer weather and the temperature is a little warmer than what it would be in my Optimal Happy Place.  (Okay.  Don't laugh.  Outdoor temperature right now is 72; inside it is 74.  Expected high today is 78.  I think the high yesterday was right around there and I got overheated to the point of being nauseated several times yesterday.)
When I woke up this morning, I did feel a glimmer of perkiness.  I didn't feel like just rolling over and going back to sleep.  I didn't feel tired thinking about what I was going to do when I got up.  
I feel a bit lethargic and sluggish right now, but I don't know if that is from poor sleep last night or from something else.
Also, with the subjective sense of not being able to get enough air, I don't know if that came before or after the poor sleep.  Is my PTB low because I am really not breathing deeply enough?  Or do I feel like I am not breathing deeply enough because I didn't initiate a whole lot of breathing on my own last night?
I really wish I had one of those things to measue O2 sats.  Do I feel like I am not getting enough air becase my O2 sats are low, or is it merely a subjective feeling with no physiological correlate?
