If I were you I would just let the wife and doctor get him some medicine. You might be surprised at the difference it makes. You'll probably wonder why you did not do it sooner.
I know of a man who did not any medicine for his son who was completely out of control with Turrets syndrome (sp?). His wife wanted to give the boy medicine and her husband finally gave in. The boy is much better now.
Ritalin IS the drug of choice for TURRETS SYNDROME.
