Thank you for letting me know about the parent advocacy group. I will give them a call. We have been on the Feingold Diet for about a month now and have seen results. The book is entitled "Why Your Child Is Hyperactive" by Ben F. Feingold, M.D. I have also noticed an immediate behavioral problem after he eats anything with tomatoes in it, as well as others have that I have spoken with. Monitoring his sugar intake on top of this diet regimin has seemed to help also. The book is not just about hyperactivity, of which my son does NOT seemed to be afflicted. It covers the common problems associated with ADD.
