Try to get in some sort of habit/rhythm. I do my school work right with/after my morning coffee when I get up and keep after it as long as I can. I have my non-fiction on the computer e-reader and my fiction on my Nook by the side of my bed for a treat before I go to sleep, but having an "area" where I work/read and that's all (not where I watch TV or do anything else) means when my behind is in that seat that's pretty much what I work on.

I have to write papers so I mostly read to help me write the papers and kind of do both at once; that way I can get an idea while reading and go write notes or something and then come back and read some more, etc. I also make copies of my pages/reading and/or write notes in the book/on the paper as I go along, etc.
