Yeah...the P10 pillows is what I currently use and have pretty much since it was released. I like to try new things and there's been some new masks released but I keep going back to the P10.
It's about as nothing of a mask as is out there and the venting is essentially silent and can't be felt unless my hand is about an inch from the vent holes.
And while it would be a nice miracle that using the mask and machine lets you fall asleep quickly....don't hold your breath.
It's just a weird feeling in general and takes some getting used to.
What you can do though is use the mask and machine while not being under the gun to fall asleep and maybe avoid that stress.
Like while awake watching TV or reading a book.
My very first night with the mask and machine was in a sleep lab titration study and it ended up being the night from hell.
I couldn't fall asleep and was worried about falling asleep and that made it worse. The air going up the nose wasn't unpleasant but it was different and just being something different caused me to not be able to sleep well.
It took me about a week at home for my brain to get to be okay with the mask and machine helping out.
I had a lot of wake ups the first month just from my brain poking me to alert me to the alien on my face blowing air up my nose.
The brain doesn't like a lot of changes from its usual routine so even if the cpap and mask is really a good thing..it's a new thing and the brain still has to come to grips with the new way of doing something.
While it would be really nice if you had a first night miracle...don't let it get you down if you don't. Those miracles are extremely rare and the people who have them don't know how lucky they are. Not impossible of course but not probable for that miracle to happen.
I think the people who have the first night miracle are the ones with really, really severe OSA and the change is so dramatic that they feel it straight away. I didn't have the first night miracle or even the first week miracle. Might call it a first month miracle if going by reduction in nocturia and killer headaches but in terms of energy levels and sleep quality...a lot longer. It was a more gradual improvement instead of an overnight improvement.
I hope I am wrong but I don't believe in sugar coating anything.

I may have to RISE but I refuse to SHINE.
