My Husband Is Very Hyperactive And Sometimes Has Erratic Behavior.

My husband is very hyperactive and sometimes has erratic behavior. It has gotten out of control and causing family to avoid being around for very long. We go to doctor tomorrow and we are thinking maybe they can give him something to settle him down to relax a bit. He is not a smoker or drinker (occasional beer) retired and needs something to help him relax. Your thoughts or opinion would great?
