Watching the telly while I'm doing my work helps sometimes...hehehe.

Also, try to arrange your day so that you're studying when your brain is fresh, that might mean getting up early to do reading, take notes, etc....might help? I used to find that I was hopeless of an evening until about 10 at night, so I would just watch telly, etc, then start and go for a couple of hours. Doesn't make sense but those late nights were quite effective for me.
