yayyyy... do you know what the triggers are? ... for me, it is usually a particular kind of stress or weird reflected sunlight, like when sun reflects off a bumper and hits my eye in a certain way...

I think it's allergies. But not to one thing so I can say, "No more coffee," and everything will be fine.

I think today's trigger was a moldy onion. I threw it out in the yard.

...I "caught" a headache this afternoon after getting home from the Magnificat rehearsal, tried going to bed, and finally gave up and took some Excedrin. That plus a big bowl of potatoes with pico de gallo and shredded cheese in it seems to have cured it...for now.
