Second, the collar isn't any new culprit as I used it last night for the first time and this set of dailies was from Sunday night's sleep. I don't know what is waking me. To answer you CG, yes the discomfort is always a dry mouth, every morning and almost always I awake around 3-4am with this occurring. And every morning I do the same thing, turn off the machine and try to relieve myself of the dryness, then fall back to sleep without CPAP. Mind you prior to waking and shutting it down I really don't recall waking. I always sleep on my back and don't turn to my side as I can never seem to keep a good seal on the nasal pillows if I try side sleeping. Once the machine is off I always sleep on my side ... and I toss and turn several times during that last hour or two of restless, (most likely apnea filled sleep).
Ok, there are several interrelated issues that need to be dealt with.
1)
Mouth breathing. CG is right: Waking up with a dry mouth is indeed a sign of mouth breathing. And even when it's not triggering official Large Leaks, the mouth breathing is leading to the dry mouth. A FFM should fix the leaks, but it may or may not help the dry mouth: A lot of air is moving through the mouth when you are mouth breathing, particularly with a CPAP, and it's the moving air that dries the mouth out. And many mouth breathers find the humidifier just can't keep their mouth moist even when they use a FFM.
2)
Sleep position, comfort, and nasal pillows. Sounds like your natural sleep position is on your side, and you are trying to change your natural sleep position to accommodate using the nasal pillows mask. It's usually a mistake to try to change things to accommodate the mask if you can avoid it. You might be more comfortable and less likely to wake up to turn the machine off if you can figure out a way to fall asleep on your sides with the nasal pillows. You are using the P10 mask. And for all that's really good in that mask, there's the irritating fact that the headgear is one-size-fits-most. And thus it is not a very easy mask to "tighten" or "loosen" in an effort to customize the fit. The P10 can also be a bit more difficult (in my opinion) to control the angle the pillows rest against the nostrils, but the angle the pillows rest against the nose is critical in getting and maintaining a good seal, particularly when you are on your side.
So let' talk about how you are putting the P10 mask on and fitting it when you go to bed. Do you just pull it on and turn the machine on and then fiddle with the pillows while lying on your back and then try to turn onto your side? Can you feel the tip of the pillows touching the inside of your nose when you are on your side? Does the headgear feel to flimsy to keep the mask in place when you are on your side? Does the edge of the pillow barrel (where the pillows attach to the frame) hit your pillow and get dislodged when you are on your side? All of these things can be overcome with a bit of effort, but we need to know more about what's going wrong than, "the pillows seem to leak more when I'm on my side."

The middle of the night wake and returning to sleep without the mask. Yes, I understand you're waking up with a dry mouth. And it makes sense to turn the machine off so that you can work on relieving the dry mouth. I also understand why you're reluctant to get up and get a drink of water since you find it very difficult to get back to sleep after getting out of bed for any reason. But you've got to figure out a way to make yourself turn the machine back on after you've managed to get the mouth a bit rehydrated. It really is that simple. And that hard. It's ok to lie in bed for a few minutes to regroup and wet your mouth. But then when you snuggle back down to go back to sleep, you need to simply turn the machine back on. And at least try to get back to sleep with the machine on rather than intentionally allowing yourself to return to sleep without the mask.
Would it help to have a water bottle on the night stand? You could then take the mask off, drink some water, and then mask up and turn the machine back on when you snuggle back down to go back to sleep. With the right kind of water bottle, you ought to be able to do this in the dark and still not worry about spilling the water all over.
One might suggest I get up and take care of the dry mouth then try to sleep with the machine but I fear getting up. Normally once I'm up, I'm up and have a lot of difficulty getting back to sleep. So I don't even try getting up. I simply shut off the machine, try to work out the dryness naturally and then fade back to sleep.
Again: There's nothing wrong with shutting off the machine and working out the dryness naturally. But once your mouth is not so dry, you need to turn the machine back on before you "fade back to sleep."
What's going on here is that you are rewarding the subconscious part of your brain for waking up when it notices the dry mouth. When it wakes you up, you then take the dang mask off and go back to sleep and the subconscious part of the brain that doesn't fully believe this is the new normal is rewarded for its waking you up. The only way you will get over this hump is to learn to turn the machine back on after you've dealt with the dry mouth as best you can without getting out of bed.
This Sunday graph shows a large leak around the time that I shut the machine off but looking at the 4 days prior to that it doesn't show the leak happening just prior to me waking and shutting it down. I'll do some more analysis with each passing day to see if it is really the norm or the exception. There ARE large leak signs every night though. Just randomly throughout the night.
You may be randomly mouth breathing. Or you may be shifting around enough to break the rather fragile seal you seem to have with the P10. Learning how to get a better seal might help some of the random leaks.
The collar isn't too bad. As Granny says it doesn't interfere with the mask. I slept last night like I always do except for a brief stint where a dream woke me around midnight. FYI I don't really dream much while I'm using the machine (that I can recall). Is that a sign of anything? I do dream but if I recall correctly that usually happens after I've turned off the machine.
The normal pattern is for us to NOT remember our dreams. A lot of people with untreated OSA tend to remember their dreams more than normal because they frequently wake up in the middle of a dream due to apneas. And you typically remember a dream only when you wake up either in the dream or immediately after the dream is over.
If you remember fewer dreams when using CPAP, that probably is a sign that you are no longer having apneas when you are in REM. If you still remember the dreams when you are sleeping without the machine, that probably means that when you hit REM and you aren't using the machine, you also have a lot of events occurring and waking you up in the middle of the dreams.
One thing I remember about my adjustment period was that I missed the fact that pre-CPAP I had very vivid dreams that I frequently remembered. Most of these vivid dreams were good dreams and none of them involved choking or drowning sensations. But once I started CPAP, I started remembering so few of my dreams that for a very long time I was worried I was not getting sufficient REM sleep. In retrospect, I know my PAP-sleep was highly fragmented at the time, but I do think I probably was getting a reasonable amount of REM. But I was no longer remembering it because I was not arousing every 3 or 4 minutes while in REM due to the untreated OSA.
