If medication alone has worked for you, that's great! But I don't think your opinion matches the medical consensus.
> For children with ADHD younger than 6 years of age, the American Academy of Pediatrics (AAP) recommends parent training in behavior management as the first line of treatment, before medication is tried.
> For children 6 years of age and older, the recommendations include medication and behavior therapy together—parent training in behavior management for children up to age 12 and other types of behavior therapy and training for adolescents. Schools can be part of the treatment as well. AAP recommendations also include adding behavioral classroom intervention and school supports. [1]
This makes sense for very young children, for various reasons, mainly that it’s hard or impossible to diagnose ADHD with reliability at such a young age, and because medication is hard to dose properly to a rapidly growing child. But these recommendations are honestly more about helping the parents cope than about treating the child’s ADHD. Behavioral therapy is more about learning how to fit in than addressing the actual problems (which are often exacerbated by the inevitable failure of such behavioral treatment and its corresponding expectations in folks with genuine ADHD).
