I ended up with a headache behind my left eye this evening.

It was a combination of factors really.
First it probably started with me not getting enough sleep last night because I stayed up later than planned.
and then it was probably the build up of stress from all the managers around me worrying about the bigwigs visiting the store.

But I was handling those rather well. No signs of a headache.

Until I got back from lunch.
And was surprised with the news that I would be training one of our cashiers to be in my department.
Which meant I had to switch gears and go into 'teacher mode'

Which is a whole different type of energy.
Energy I hadn't planned for.

So the ache started behind my eyes about an hour before I was off. 
The ache of 'you're tired you need sleep.'

And so I crashed once I got home.
But the headache got slightly worse. 

Thankfully a hot shower, tylenol, taking out my contacts, and a heatpack have helped it to fade again. So woot.
