Woke up this morning with a pain in my head

For the second morning in a row I awoke around 3:00 am and couldn’t get back to sleep. Yesterday I attributed it to the fact that I wasn’t using the CPAP (because I couldn’t breathe through my nose), but that was not the case this morning. This is usually the time that I start deep sleep which can lead to apnea episodes, especially when I’m not using the machine. I’m not sure what the explanation is this morning.

Since I’ve been awake, I’ve had the words “woke up this morning with a pain in my head” floating around in my head and couldn’t figure out to which song they belonged. Turns out those words belong to many songs.
