One of the most challenging aspects of the central sleep apnea I'm dealing with is the feeling that I'm being sucked into a black hole where time has no meaning. The sense of time telescopes, so that last week feels the same as last month or last night. I've found myself repeatedly referring to a calendar to figure out how long ago something happened, because my own sense of the passage of time is unreliable. It resembles how I imagine it might feel to fall into a black hole, where all sense of time and space is warped beyond normal experience. And it seems to be getting worse.
I have a sleep study scheduled for this coming Wednesday the 15th. After that, through whatever application of medical technology my doctors might bring to bear, I hope to leave, at last, the twilight world between sleep and wakefulness in which I've lived for the past few months.
