Ended up with a headache this evening. 
Behind my right eye.

I'm pretty sure it's just from...the strains of the day.
Like.
I ended up working a split shift.
So I worked in the morning and the evening.

And I think the strain of having to be social so late in the evening got to me.

Thankfully it didn't seem like a major headache
As it faded when I took out my contacts and got some food to eat.

But yah.
Slight headache.
Could have been more major.
But thankfully it doesn't appear to be so.
