My parents used an all natural solution to ADHD when I was a child: Discipline. They discilplined me and it taught me to discipline myself. Also playing sports really helped me to focus (and still does). As I got older, I found other methods, certain music low in the background and Fish Oils have helped me immeasurably. I don't want to give a dosage because I work with my doctor on that and it may be different for others, especially children.
