Iancdub88,
Here's the next post with the careful analysis of your data.
3:10 AM to 5:20 AM
This roughly 2 hour chunk of the night looks like this:

At this level of zooming, it looks like it took you 7-10 minutes to get back to sleep after you turned the machine back on around 3:10. Was that break a bathroom break? At any rate, at this level of zooming there's no evidence that you got caught in a nasty SWJ cycle unable to transition to full sleep.
There are possible arousals/mini-wakes at the following times: 3:56, 4:07-4:10, 4:24, 4:44, 4:59, 5:08-5:14. My best guess is that the arousals at 3:56, 4:24, 4:44, and 4:59 are just you turning over in bed: These are all very short in length. The stuff between 4:07 and 4:10 is probably a short wake. And the stuff between 5:08 and 5:14 is probably a real wake. And it may be long enough to be a problem since you report waking up early and not being able to get back to sleep. More on this in a bit.
Again, there are some flow limitations that lead to pressure increases. And the flow limitations seem to smooth out in response to the increase in pressure. Again, it may be that these flow limitations are REM related or supine related, particularly if your OSA was worse in REM or on your back during the diagnostic sleep test. And a bit higher minimum pressure might just prevent them from happening, and that might make you sleep a bit better. (As long as the increased pressure doesn't cause a problem like aerophagia.)
5:10 AM to 7:30 AM
Here's what this 2 hour and 20 minute chunk of the night looks like:

The first blip is the end of the restless period between 5:08 and 5:14. Then you've got what looks like arousals, wakes, and/or general restlessness (SWJ) at the following times: 5:28-5:31; possible restlessness between 5:31 and 5:48 (need to zoom in on this closer); a wake at 6:05--6:10, with possible restlessness starting as early as 6:00 (need to zoom in on this closer) and possible restlessness lasting until as late as 6:15 or 6:20; restlessness or a wake between 6:40 and 6:47; a clear wake at around 7:05, with evidence that you never fell back asleep before turning the machine off at 7:30.
Even at this scale, it's easy to put this together with your self-report of waking up about an hour before your alarm went off and could not get back to sleep. You may have dozed here and there for 10-20 minutes between 5:30 and 7:30, but it doesn't really look like you got as much as a 40-60 minute stretch of real sleep after 5:30.
Here's the period between 5:30 and 6:10:

At this level of zooming, it looks like you might have gotten some actual sleep between 5:45 and 6:05. But 20 minutes is not long enough for a full sleep cycle. So your brain may not have recognized this 20 minute stretch of sleep as "real" sleep while you were lying in bed thinking you could not get back to sleep.
Here's the period between 6:10 and 6:50:

At this level of zooming, it looks like you might have fallen into a very light sleep around 6:15 or 6:25, but again, you didn't sleep long---it looks like there's a clear wake just after 6:40. So again, I can see how your brain might very well have felt like you didn't fall asleep at all during this period.
Here's the period between 6:50 and 7:30:

At this scale it looks to me like you never really got back to sleep after 7:05, or if you did it was only for a few minutes here and there---nothing continuous enough to feel like real sleep. And it's questionable how much
continuous sleep there is between 6:50 and 7:05.
Now sometimes when you wake up and allow yourself to pleasantly daydream and doze for a while before getting up, you'll see these same kind of SWJ patterns. The difference, however, is in the
subjective feeling about the overall quality of the whole night's sleep. When you wake up too early and you
try unsuccessfully to get back into a sound sleep to get one more full sleep cycle, your brain has good reason to interpret what's going on as "tossing and turning and not sleeping well". But when you consciously allow yourself to lie in bed knowing that you're half-asleep and half-awake because you're pleasantly enjoying that time in bed before you make the decision to get up, your brain is apt to interpret that period of SWJ very differently---it's likely to think of it as a relaxing bit of dozing before fully waking up and when you do get up, you're likely to say that overall you slept pretty decently.
Since you're not feeling well and since you report that you were
trying to get back to sleep after you woke up an hour too early, it's reasonable to assume that all this potential SWJ in the last couple of hours of the night is problematic at this point in time. The problem, however, is not that the CPAP isn't working: When you are asleep, it is doing an excellent job of preventing your apneas and hypopneas from happening and it's dealing with the residual flow limitations in what looks like an appropriate way. The problem is that your brain doesn't want to be awake, but your brain also won't allow itself to get fully back to sleep.
Sometimes that can happen because the
body feels sufficiently rested. As a new PAPer, it is possible that your body has gotten as much sleep in 7 hours of half-way decent sleep that has not been interrupted at all by the apneas as it used to get in 9 hours of apnea-interrupted sleep. So the body is saying to the brain:
I've gotten enough sleep! even though the brain is saying
No I haven't. In time the body figures out that getting 8 hours of better quality sleep (without the apneas) is far better than 9 hours of apnea interrupted sleep, and it naturally starts sleeping longer with the CPAP. And of course that pleases the brain. But until the body sorts out that it needs/wants more than 7 hours of half-way decent sleep that is not interrupted by apneas, the poor newbie PAPer is left with problem of "I'm waking up and can't get back to sleep". In this case, it can be best to humor the body and just get out of bed when you can't get back to sleep and it's within 60-90 minutes of when your alarm goes off anyway. Use that time to do some kind of quiet activity and
if you start actually feeling like you are going to fall asleep, then go back to bed and fall asleep with the mask on your nose.
