Thanks for all the help with posting links to data. Here is my response, with some links and attempting to answer the questions that were asked in earlier comments:
I use a RemStar Auto with A-Flex, and my range is 9 -15 cm. I don’t use the ramp feature. I do use the A-flex.
The clear airway events seem to be as I’m falling asleep, and then they often occur again in the last 90 to 30 minutes before I wake up in the morning.
As for how unstable the flow rate is during these events, I’m not sure how to read that. I see the graph of my flow rate on Sleepyhead; what does “unstable” look like?
As to the number of RERAs and such during the breathless periods: The night when I first posted this, I had four clear airways, four hypopneas, and two RERAs in the space of about fifteen minutes. That was right when I was getting down into sleep, and it kept kicking me back awake until I was no longer sleepy. Here are screen shots of data from that night (it's not for the whole night, because after getting up to look at the card data, I didn't push the card back in the whole way and so the rest of the night didn't record )

My AHI for an entire night is typically between 1.5 and 2, but when I have multiple events that wake me up over and over and over until I'm wide awake, seeing a low AHI the next morning doesn’t exactly erase the fact that I lost my first 2 hours of sleep. Also, my Sleepyhead Software doesn’t seem to be counting RERAs in my AHI, but my RERAs are definitely contributing to the number of times that I am roused out of sleep.
In addition, I wear my mask while I’m reading and getting sleepy at bedtime, plus I often wake up and lie awake for an hour or so in the night, so the math on my AHIs is probably thrown off…I’m sure my AHIs would be a little higher if it measured the time that I was actually asleep vs. the total number of hours that I have the mask on and running.
I typically have more hypopneas than anything, with RERAs and clear airways coming in second.
Here are screen shots of typical data from another night. As you can see, still a lot of events clustered together. On this nights, I don't remember waking up.

Sometimes I will have nights with almost no events at all (perhaps 2 the entire night and no RERAs). Other nights look like this. Some nights I have trouble falling asleep because of it for 1-2 hours; other nights I don't. It does tend to happen more often when I'm anxious or tense, but not always.
I am anxious to find an answer for this and resolve it somehow. It's affecting my life because it makes me lose sleep at random times, and it prevents me from doing certain things like taking night-time cold medication or Dramamine or other meds I might need from time to time that affect droswiness (as they tend to make the breathless waking symptoms worse and last longer).
Thanks for any help you can give! If anyone has suggestions of how I might get my doctor to better understand my concerns, I'm open to it.
