I ultimately homeschooled and I spent a lot of time on various parenting lists. Nutritional supplements actually have a good track record of calming down wild kids, but that isn't a standard recommendation and gets dismissed as woo if you talk about it.
If you are interested in that angle, there's interesting research and discussion related to nutrition and prison populations here:

Over the years, I have seen other articles that suggest that ADHD makes one a better soldier or whatever. I'm not really surprised by the research cited here concerning ADHD genes and things like migration and occupational outcomes.
Once upon a time, we talked about personality differences, saying some people were shy and others gregarious. Now, we diagnose shy people with conditions like selective mutism and we say gregarious people have no filter and diagnose them with conditions like ADHD. I realize some people really suffer. But I think it makes vastly more sense to take a nutritional approach and also consider what people are well suited for and help them find their niche instead of medicalizing and medicating everything under the sun.
