I'm guessing that i need to drop my pressure

That is weird that dropping the pressure created more centrals!!

Oh, and that would be super annoying to pay out of pocket for a sleep study and then have a good night. Ugh. Well, I don't know what else to suggest other than a journal to find a pattern.

And...for the record...I was giving the CAI James's doc quoted as a benchmark for the op as to when he would prescribe an ASV. James's treatment we are perfectly happy with.
