I typically go to bed around 2, get up around 10. That varies widely. Always has.
I have the dx of OSA with the side benefit of pressure induced CSA.
I have been at the current pressure a very long time.
My OA index is always the highest with the CA index ranging from 0 to 1 or so. Rarely is the CA higher.
In October I started nodding off every afternoon between 2ish and 4ish. I rarely gave in and napped. I was giving myself whiplash nodding my head. I don't mean just "golly gee, I could take a nap!" but actually falling asleep playing an action game. This was completely out of character. No medication change, nothing. Then, it seemed to pass and I was staying awake all day. Then it came back a few weeks later, went away, and is back again.
The only difference I see in the data is during the time I was greatly desiring naps, my AHI climbed slightly (never over 5, mostly in the 3s). But the biggest difference is the CA index increased to the point it surpassed the OA. One day it alone was just under 3.
So my question is: if my AHI is still under 5, if the primary change is an increase in central events, why am I craving a nap? Or is the slight increase in the AHI overall the main cause?
Attached is the 6mos overview to show the increase as well as the "wave" for the past few months.
Take a deep breath and count to zen.
