Have you tried caffeine or St. Johns Wart or any other natural supplements? Do a little research online first to see what might work for your son. Also, I know most parents don't want to medicate their child, but as a teacher, I have seen medication majorally help many kids. Not only does it help their grades, but their confidence, self esteem, peer relationships and overall happiness. Try all non-medication routes first, but do keep an open mind to medication if needed later.
