How can I solve my problem with random object!

My problem - This semester I always have been getting health problems, jaw disorder.
Random object -Text Book!

Ironically, I have to solve my health problem with object that might cause the problem.
However, I will never give up to solve it. Let's see how I arrange my disgusting problem.

Although reading a book is not good for Jaw disorder(because it makes neck muscle tired), I have to keep reading a book for my studying. So, I cannot throw it away. I will use it as massage bar to relax neck muscle.

In addition, if I read it ahead of class, I will not be under stress so that  it prevents a recurrence of an illness.
