Hi Jerry,
I am a registered dietitian that specializes in treating adhd, tourettes, and autism. go to amazon.com and get a book by dr. nambudribad titled say goodbye to allergy related add/adhd. you will be very happy once you read it and find a practitioner in the area. i have amazing success with my clients and this protocol. i also have a son that HAD tourettes and adhd. he still occasionally gets hyper until i figure out what the trigger was and treat the allergy, other than that he is awesome.
good luck,
kim marin
