I believe discovered the culprit.

Last night I replaced my FFM for nasal. I got up at 3am took my SD card to my computer to check the reading.
It read 6.X. What does that mean??? Starlette has a cold Makes sense now.
Events would rise since my throat has been feeling dry and a slight tickle in the back of my throat for the last couple of nights, along with a slight tickle and runny nose. I just didn't put 2 and 2 together. Like any other cold, I just have to ride it out.

I feel embarrassed. What can I say? One panicks when the events (AHIs) rise and you can't understand why and your working day depends on you getting good therapy. My head feels clearer today and not so much a walking zombie as yesterday.

Thank you for listening

Sometimes the culprit is so close to us we can't see it and instead go looking in other places. We simply try to over analyze things sometimes. No problem and another lesson learned which makes the experiment still a success because it offers additional information..even though it wasn't what the original experiment was designed to do.
