Sleep Deprivation

I suppose it's only so much to expect to be able to stay up until 4am reading and then get up a little later at 10am to go out and grab myself food.
Sleep deprivation is definitely not a good thing to do when trying to avoid headaches.
I ended up staying up a bit after I got back from food when I'd intended to go straight back to bed, and so unsurprisingly ended up with a sleep deprivation headache.
Unfortunately heading to bed for a couple of hours didn't solve that headache issue though it should have since I knew the cause of it was lack of rest...
But thankfully some Excedrin solved the problem. Yay Meds.
