Ehh, Although PhotoReading never worked for me, I have read enough on forums about similar, One thing's for sure: There can never be such a thing as the brain "being overwhelmed"; I suggest that well, Check up a program called Brain Wave Generator and play the concentration brainwaves, They are Beta ones which are going to help you concentrate. Also check up a brainwave recording called BrainFlex V2.
One Question: Did PhotoReading EVER work for you?
