For a long time I had to adjust my reading level down to very light reading for limited times. I could handle children's chapter books (I think aimed at the upper elementary/middle school age group). I've improved a lot but sometimes when I need a brain break I just rest and/or do light reading. For me that is restful (I am a serious read-a-holic). One of the ways I knew I was improving was my ability to gradually increase the reading level, part of the time I can read like a grown up. Happy, Happy! I don't think it has changed much for the past 6 months or so. Just like everything else, take it slow and cautious, you'll figure out what works for you.
