Okay, let me finish up this "off topic" ramble before someone gets the wrong idea.
The doctors all said it didn't have anything to do with it.
It was brought on by three days of complete exhaustion which would normally have brought on a ferocious migraine, but this time the blood clot hit the optic nerve and killed the vision in the bottom of the left eye.
No biggie. The eye still looks the same, and the right took over the peripheral vision for the left. I don't even notice it anymore.
At any rate, it's too coincidental that the migraines stopped at the same time.
