"Before using CPAP and sometimes even with CPAP, as I am falling asleep I am jerked awake by a total body "flush" where it feels like adrenaline pumps through my blood for 30-60 seconds. Almost like I am vibrating. Not shaking, more than tingling, and not a hot flash. I suspect it has to do with having an apnea: as I gasp for breath the oxygen flows back into the bloodstream causing this "flush." The doctors I have consulted about this say, yes, it could be the oxygen, but no one has said either they have experienced this, or they have a patient who has. I don't know for sure if I have an apnea right before this happens. I guess I am asleep during the apnea and only wake up for this weird, scary feeling.
I would love to know if others can relate to this. Or can help explain what it is. Thanks."

How long have you been on therapy? As jnk states apnea or any other health problem puts our brain on alert even when we may not noticed anything. Sometimes it may take time for our brains to believe that the threat level is gone. Studies have shown that it can take up to 6 months for our brain to BEGIN to let it's guard down.
Do you have any realistic dreams during these odd events? Have you ever experienced any type of sleep paralysis or something that may feel like an out of body experience?
Treatment for UARS is often basically the same as for OSA. In fact, not every doc draws the line between the two conditions in the same place.
But the human body is complicated. All of the things mentioned in this thread can interrelate and play off one another. So the fact that a doc won't say what it is may be just understandable humility and modesty of the doc.
Sleep is mysterious and not well understood on some levels. The hormone system is complicated. Sleep apnea and UARS are still not as well understood as hopefully they will be one day.
So, it could be that in the time when you are transitioning into sleep that you are having some pauses in your breathing, which is natural. But it may be that your body is mistaking that natural transition as something more serious and is reacting hormonally. That hormonal reaction can cause other hormonal reactions related to sex hormones. All of that can cause a bit of a mini-anxiety-attack during sleep. Any drugs at all during the day, even a cup of coffee or a few sips of wine, can interact with all of that. Emotional stresses from the day can play a role too.
If they are happening less frequently, that may be an indication you are headed in the right direction. I know I REALLY hate that vibrating feeling, myself.
You may need to do some experimenting with pressure (as in more of it) and may need to give it a little more time. If you aren't feeling as you should, and you run out of things to try on your own, you may need to be more vocal with your primary doc and sleep doc to see what else you might need to try in the way of different kinds of machines or other.
Don't resign yourself to anything. Keep trying things. Well-treated OSA is something that only involves a machine at night. Maybe not a fun thing, but no biggie, really, either. So you need to be sure you are being well-treated and try things, like making dinner time earlier and not eating past a certain hour, or rigging something up for staying off your back, or trying a different mask, or, well, anything at all to change your approach. If your sleep hygiene is good in all respects, you may need to speak to a sleep specialist that specializes in changing how you THINK about things. But there are many, many things to try, so try to make a bit of a game out of it to solve the mystery of what you can do to improve your sleep.
If any of the above is irritating to read, feel free to ignore it. I'm just throwing around ideas.

Everyone has to make his or her own call on whether to change his or her own pressures. I generally recommend keeping a sleep doc in the loop, especially if someone is the least bit hesitant or unsure. My sleep doc doesn't mind at all if I change my pressures, but he knows my situation and condition, which may be very different from yours.
If it was me and my doc was OK with me running a range of 8-12 and I was frustrated with my results and my 90% pressure on my ResMed auto was close to ten, I have got to say that my choice for myself would be at least to go ahead and put my base pressure up to ten, just to see if that improved how I felt.
My reasoning is that if my doc doesn't mind the pressure hitting the 12 cm mark, he obviously doesn't mind if I keep it from going below 10. But that is just how my mind works. Others might make a different choice.
I might also say that if I had trouble getting to sleep or had trouble waking up during the night, I might limit my pressure so that no automatic titration, or movement of pressures, was taking place at all, since some light sleepers feel better with straight pressure rather than varying pressure.
To my way of thinking, any doc that doesn't mind it if my machine chooses my pressure shouldn't mind it if I choose my own pressure within the range he trusts the machine with.
All that is to say that if I found myself in your shoes right now, I would likely put my machine in CPAP mode at a straight pressure of 10 cm for a week or so to see how that felt instead of the auto mode 8-12.
Again, though, I'm just a patient, and this is the Internet, so my views have to be filed under "one opinion from one non-medical guy on the Internet"! :-)
