Have you considered any Diet changes for ADD. There is new research out now that says that changing the diet can really make a difference. For example, eliminating sugar products as well as refined carbohydrates(white bread, etc). Also, some children have food allergies or food intolerances which show up through ADD. When those suspected foods are eliminated for a few weeks, there have been noticable improvements. For our child,we eliminated dairy and sugar and he doesn't have any problems with ADD. Good luck.
