Painful Wakeup

I had a headache when I woke up this morning.
I don't know why. 
I was comfortable.
Relaxed.
So it was either because I woke up too abruptly or I didn't get enough sleep and woke up at the wrong moment.

In any case
The headache didn't leave right away.
*exhales*
But thankfully it did fade when I took some Excedrin. 
Thankfully I didn't have to work my entire shift with an aching head.
Because that would not have been fun at all. 
*shakes head*
