Hi A. -
I have been using this program for almost 2 months now. It has made a huge difference in my 4 year old's behavior. Although I don't think all the items that are excluded in the Feingold Program are what causes his issues. Ours seems to be more focused on the food colorings and flavorings. I was hesitant at first to spend the money, but it was worth the cost to us (and my sanity) - it can be difficult to stick to if you child goes to preschool, b-day parties, etc. Also, the Today show did a story on food colorings and flavorings and hyperactivity about 2 weeks ago, so it was nice to see more people getting on board with this. Good luck!
