Reading a computer screen and then flash cards and then a computer screen and then pages and pages of outlines upwards of 18 hours/day for a month can give me a headache. With a little over a month left, I had to take a break and go to the eye doctor today. Yup, astigmatism*. AND, one eye has vision that's twice as bad as the other! How did I not notice this before? Cute new glasses arrive on my face next Friday.
* = I really wish I had an illustration by Jordan for this. She's a good friend and excellent medical illustrator.
