Here's a reply I posted under Other Stuff on natural things that you could try for aggressive and hyper behavior:
During a counseling class one mom of a 7 yr old told me that 5HTP changed their lives. It is a plant-based natural substance that helps the brain produce seratonin (a calming thing). I am trying to use it more with my son to reduce his tantrums. Another thing that I give my son is melatonin. I give it to him if he is having a really hyper evening. (I get it in capsule form and put it into his juice boxes--it has no taste). It puts him right to sleep and therefore allows us to go to sleep and get a fresh start dealing with him the next day. There is some controversy over dosage so try to give the least amount that will work.
