I think I drink plenty of water throughout the day...I'm starting to suspect that it could have a hormonal component to it. I better not get full-on migraines like some of my friends have when they reached menopausal age. I've had a history of migraines in the distant past which seem to have been caused by working in a photo lab around all the chemicals. They would always start with the crazy aura thing; I haven't had one in a very, very long time, at least! Just plain, old annoying throbbers!
I'm going to go drink some water now...
