I haven't been able to read a book in three years for the same reason. I was once a voracious reader, and now I have literally hundreds of books and absolutely no desire to try to get into one. It's SO frustrating, and I don't know what the answer to it is.

Maybe just take things one page at a time?? Read it, try to understand it, then get up and walk around for a couple of minutes before going back and trying the next page. I'm not a student so I don't HAVE to read much other than short magazine articles, which I do OK with. My most recent job required me to read and memorize massive amounts of material, which didn't last long as you might've guessed.

Wishing you the best of luck in your continuing academic career. I wish I had better advice for you. Please keep us posted.
