(no subject)

Once every couple of months I'll get a crushing, so-bad-it-literally makes-you-throw-up headache, usually centered in my forehead and temples. I wish I knew what caused them, so I could figure out how to avoid them (it's not caffeine withdrawal, not caused by my glasses prescription, not a sinus headache... possibly they're migraines?)

I also wish they didn't inevitably start at work, where "not continuing to spend the next few hours staring at an LCD computer screen" is not an option.
