trailrider: Don't worry about an occasional CA. I bet the duration of that CA was just over 10 seconds -- am I right?
Most of us using PAP have an occasional CA of short duration.
Some people during the start of therapy have a number of pressure induced CAs that abate with time.
The machine will ramp up pressure in response to snore, flow limitation, hypoapnea and an OSA. You may not have had a OSA or hypo -- but if you look at the snore and flow limitation graphs -- I think you'll see a reason for the ramp up in pressure. Snore and flow limitation are precursors to a OSA event; and the machine tries to anticipate and prevent them.

It also might be something completely unrelated to apnea or CPAP. I get those symptoms when I'm dehydrated.
I want to encourage you to hang in there with it, sometimes it takes your body a while to get used to this new way of sleeping.
Good luck to you as you continue your CPAP therapy.
Try to stick with it. Everyone adjust differently and feels different benefits at different intervals.
