My experience is greatly improved on autoset. Leakage is reduced and I'm not waking up in the night with dry mouth, not waking up at all for that matter, and the AHI reading is in the same range, .6 more or less. I have an EPR setting of 2 on my machine and have set the autoset range from eight to 12, knowing that 12 is the high end based on the doctor's review of my stats. I reduced the ramp time to five minutes and will likely put it to off in the near future. So all is good. It's taken me a while to appreciate that ultimately I'm responsible for knowing the process and what is working best for my sleep and night time comfort.
Bit of a hiccup on downloading Sleepyhead. Got a pop up telling me I can only open Apple approved software, but will go into preferences and sort that out in the near future. Next step for me is start reading and understanding the data.
This is a terrific place with lots of helpful personal experiences and technical support. Good on all of you for stepping up.
