You definitely need to take breaks every once in a while. If you study every single day for hours at a time, you will burn out eventually and stop retaining information. When I was studying for my previous parts, I tried to notice points in my study sessions where I was just simply reading text / hearing (not listening to) lectures / and staring off into space when working MCQs. Once that happens, you are done. There is no sense in sitting in front of your computer for an hour staring into space. That time is better spent resting.
Quick and simple answer: Give yourself breaks here and there and you will feel better and most likely perform better. Obviously when you get closer to your test date, step it up a bit, but still take small breaks!
