Oh, and as for how you felt in the morning? I (personally) would discount it and see if I felt the same way for 3-4 days running. At my age, I can simply hurt myself while asleep. I've been dealing with joint pain for so many years that I change position very often and do not wake up any longer due to it, unless I don't move often enough, then the pain wakes me.
As a new user, there are many changes to become used to. I can honestly say that with a good mindset, you will get used to it, and get to the point that you can't sleep without the machine.

Thanks me50. All good thoughts which I need to look at in situ. There is no real sign that I do sleep with my mouth open wearing the Nasal mask but I had the same thought myself and tried a chin strap which didn't help with the problem, but did give me sore teeth!! I am not sure about routing the pipe over the headboard (my wife having spent a fortune on re-modelling the bedroom) but will have a good look at it later tonight. I will also have a look at the masks you suggest as possibilities - there aren't many as small as non-intrusive as the wisp which makes some of them difficult for me to sleep with without causing leaks in the night, so all suggestions are welcome. . My H5i is set lower than yours as I get rain-out in the mask above 27 degrees C which I think is due to the short length of un-heated pipe which comes with the wisp mask. I have just bought a ResMed "Huggie glove" for it but not yet tried it.
Thanks for the help
When I wake up early and just lie in bed with the mask on, I find my breathing pattern is sometimes a broken rhythm, and the S9 Autoset will start to do its thing, sometimes it feels like a rapid, oscillating pressure surge. Kind of a pulsing.
If I check the Sleepyhead charts, I can tell exactly when it was that I woke up because it shows a lot more apnic events from that point until I go ahead and get up.
