You all might want to look into Nootropics, which are unclassified, they are considered "smart drugs" but basically very similiar to Ritalin and Adderal.

They have very little in terms of side effects and instead of paying $300 for a bottle, it's like $8 in powder form. These are a lot stronger than vitamin supplements, you don't want to take too much.

but speaking of which, Omega 3 is actually a big deal for ADHD sufferer's.

I'd recommend reading up on it if you haven't done so.
