While I am not a very experienced PR I did have the same things happen to me when I first started to use Photoreading after I went through the Home Study Course. I did see awhile back that this was fairly common when first starting out, but I cannot find that post at this time. For what it's worth, the headaches felt almost as if it were a "brain cramp" rather than a headache. After about a week (and Photoreading 8 books) the "headaches" seemed to go away. My suggestion, keep at it for about a week, if it is bothering you than try to PR shorter books and only 1 book a day to help reduce the strain on your brain as it begins to make those new connections that PR is causing it to make.
