Turns out that I do not have sleep apnea, so I went through the multiple sleep latency tests on Tuesday (measuring how easily I fall asleep during the day).
After monitoring my sleep overnight, they woke me up at 6am to tell me I couldn't go home yet because I needed to take naps every two hours. Once I fell back to sleep, they wouldn't let me sleep very long. Because I experienced a REM cycle during my second nap, I had to stay until I finished all five naps or had another REM cycle, whichever came first. Having two REM cycles during the naps indicates a high chance of having narcolepsy, apparently, but I only had one.
This was a lot more tiring than it sounds!
I will get the results when I see the sleep specialist after the holiday. I'm looking forward to a night of uninterupted sleep, assuming that my husband doesn't snore tonight and he keeps the TV down, of course! tee hee!
