Hi, I am sorry I took so long to answer such an important question. We are on vacation in the High Sierras and computer time is tough. I have a ton of resources that can help you. But, I need a bit more info to narrow things down.
What kind of a doctor diagnosed your son? Were his teachers questioned?
You said, "some days I don't think he needs medication and other days I feel like it might be helpful if he were on something. " Many times kids will do much better at home then at school.
So what do his teachers think about how he is doing?
As I said, I have a lot of resources to share. Here are two that you might find helpful.
