Yesterday, I think I had my first migraine, or something similar. Except there wasn't a lot of head pain, just some queasiness and the freaky, freaky shimmery edges in my vision, that turned into blurring at the edge of my left eye. It went away in about an hour, the vision thing, but I went home from work and slept away the afternoon, in the hope that would help. Which it did. But I am still a little freaked out.
I am going to get glare protectors for my computer screens at work, since I think that was probably a big part of it.
