I always feel this way. I am constantly craving education. Even when I was not in college (took a break for 2 years till this fall) I was constantly learning Japanese and studying geography, particularly the countries of Africa and Asia. My brain needs to learn every day to be satisfied. I don't attribute this to any medication I'm on, although adderall helps me focus on the material I am studying. I think some people like us are just born this way. Constantly needing to learn. It's not a bad thing.
