David, I have sleep apnea and have been through the sleep study/C-PAP cycle. When you go for your sleep study, see if your hospital can do it as a "split" where they monitor you for the first half of the study and then if you need C-PAP, they apply and titrate it for the remainder of the night. That way, you don't have to go twice. My sleep center doesn't do it that way. I had the first sleep study and then a second with C-PAP titration. I too have a machine with a memory card that shows how compliant (or not) I am. My machine also has a feature that starts the pressure low and then ramps up to the appropriate setting. I can't fall asleep with it on at full pressure. I have a co-worker who has nasal pillows instead of a mask - less confining. I don't mind the mask because it's small. It has helped a LOT in that I don't awaken feeling as though I could go back to bed and sleep for another 3-4 hours. It has taken me awhile to get used to sleeping with it. My cat is not too keen on it because she likes to sleep with me, but I can't do anything about that.
