I don't get a throbbing headache, but a runner's high type feeling. Of course, that could be the Hot Cocoa and Caramel Brownie that I always eat at Barnes and Noble.
No seriously, I do get a feeling of incredible calm, kinda like after you meditate for a few minutes.
Also, maybe it's the defocusing thing, but when I look up after photoreading I'm kinda spaced out (duh). Ive almost ran into people when walking out of the bookstore.
