I was dx'd with adhd and on Ritalin and I was mainly very delayed and hyperactive. My son wasw dx'd with adhd at age 3 and put on Ritalin, then Concerta, then Adderall and many others. They made him all sick when they wore off in his system and one day at age 5 I caught him attempting to drink some wine in an attempt to self medicate as his Ritalin was wearing off. I met a hollistic doctor (the best one yet!) He suggested using Omega vitamins only in lieu of stimulants in conjunction with exercise, deterents, distractions etc ... when he felt "out of control." He is an honor roll student now and I think that all or most of us with adhd must find our niche in ife and use exercise as a great vice to overcome so much of our additional energies that build up and create so much havoc in our lives. Take care.
