I get these headaches and I'm so tired of them.
Generally the source of my headaches is as follows:

• lack of sleep
• lack of water
• lack of food
• stress
• too much reading
• too much tv
• being upside down
• playing too hard
• laughing too much

I kid you not. Honest to goodness I can literally trace headaches back to those things. I've been alive 19 years and these have always always been the causes.
Look again at that list.
That's, um, like everything. Like, what could I do for an entire day that isn't going to give me a headache eventually?!??!! I have a perpetual headache and it's pissing me off.
Take today, for example. Bloody freakin' headache all afternoon and evening. It was a bad one. Borderline-migraine. It could have been from the lack of water, too much reading, or too much laughing. But, ya know what? It's gotten to a point where I don't even bother finding the cause of my headaches. HA, they're always there so who gives a darn?!
I hate my headaches.
Yes, I complain a lot and have a low pain tolerance but believe me on this one, I'm usually in pain from a headache.
