Answer:
Many parents have tried nutritional methods, such as taking sugar out of the child's diet, before they seek medical attention. A small body of research has suggested that some children may benefit from nutritional treatments, but there are no well-established methods that have consistently shown to be helpful to most children with ADD/ADHD.
Monitoring a child's diet gets more difficult as a child gets older and more independent, making the research difficult. Also, delaying the use of proven, effective treatments, while trying things with unknown effects may be harmful to children.

An appropriate diet, when combined with supplements, such as Omega 3 fatty acids, and a structured lifestyle, with a system of rewards, and punishments, such as removal of privileges, helps a great deal.
An increased incidence of abuse of cocaine, crack cocaine, crystal meth, and other amphetamines has been reported among users of Ritalin, and other amphetamine related medications, which may well predispose them to later abuse street drugs, with all the adverse consequence it entails.
Take at least 4 Omega 3 fish oil supplements, daily: (certified free of mercury) it is best if consumed with an antioxidant, such as an orange, or its FRESHLY SQUEEZED juice. If vitamin E is added, it should be certified as being 100% from natural sources, or if it is synthetic, avoid it.
Eliminate, or minimize sugar use, replacing with xylitol, or stevia which you can get from the health food stores. Avoid artificial colors, flavors, sweeteners, preservatives, and monosodium glutamate.
Minimize highly processed grains, and use of alcohol .
