I'm not surprised I got a headache.
I'd stayed up until 4am the past couple of days working to get a fic finished and posted as it was my due date to have it posted yesterday. 

It also didn't help that I had work this morning.
So I only got a couple of hours of sleep.

Which I somehow managed to function well enough on.
But I knew the headache would come.
I get headaches from too little sleep.
Add the stress of work on top of that...
And it's not a good mixture lol.

It didn't hit until later in the day though.
Thankfully it didn't get bad until later in the evening....
But yah. It's bad enough that I can't focus....
Hopefully it doesn't keep me up all night. But...it is the type of headache to do just that. *exhales*
