That's interesting - I find myself using music to 'regulate' myself a lot. Usually I'm able to let it exist in the background, but when I start paying attention to the lyrics, I switch to Bach, or Mozart. Rachmaninoff is a nice blend of keeping me awake, but without lyrics I end up listening to.

I've actually never been medicated, but I've always had problems with tasks that I wasn't intensely interested in. Always been a daydreamer. I don't think I've ever read an entire textbook, for instance. I'll force myself to concentrate and slog through a paragraph, just to find my mind is in some other world by the end of it and have to reread it. I don't have this problem at all with fiction, I've finished 700 page novels in a few days.

Thanks for the advice, I'll definitely bring this up in my next visit to the doctor.
