Thanks, you pointed me in a good direction. My sleep study only reported the figures for when I was lying on my back / supine. When I questioned them about SIDELYING data from my sleep study, turns out my values ere GREAT and NORMAL as long as I stay off my back. I will invest in some good sidelying...

I am using a Dream Station CPAP. My initial setting was 12 for pressure, with my AHI (apnea hypoxia index) around 2 consistently. I did a trial of only sleeping on side, NO backlying, and has been able to reduce pressure down to 4 with AHIs staying roughly about 1 -2. No increase in problems at all....
