Hi farscape, well it can take a long time, and these are very early days, but persist, who knows, you may actually get like my cousin who prefers his CPAP to nothing :))
One reason you wake after 4 hours may be that your body isn't used to getting much sleep with the apneas and 4 hours quality sleep may be more than you were getting with a much longer night of apneas. Do you sleep after removing the mask?
It certainly is worth trying the Nasal Aire and also going to a site like CPAPman's if you haven't already, to see all the different types. It isn't just the type of mask, there are different types of headgear as well.
I haven't made it to the full night either and I've been trying since July, though I think I am doing unusually badly. it really is quite something to get used to, isn't it.
My main trouble seems to be my nose interior reacts to the CPAP by swelling during the night so I end up fighting to breath,the very opposite to what it should be doing!
i have been trying the Mirage ultra mask which I alternate each night with the Breeze nasal pillows.
I really need a different headgear for the Breeze, though, as I find it hard to lie on my back with.
I am hoping to try the Oracle mouth mask,I know it won't be the answer to everything as I may find my dehumidifier can't deliver enough moisture to keep my mouth comfy,
There is such a variety of stuff to try, but like the nasal Aire, the Breeze Nasal pillows deliver a much more concentrated blast of air into your nose and it can feel colder and stronger, a humidifier is vital i think, and you might need to turn it up.
It helps to be secure with your titration which I hope was done by a proper measurement and not by the crazy 'nurse listens at the door now and then to see if you are snoring' method I suffered as I'm not sure if half my problems aren't the pressure being wrong. I am someone that doesn't snore despite apnea, so they really weren't doing any titration on me at all.
Good luck, anyway, it is a pain, but worth it!
