don't know how but it sounds like he needs to see the doctor its not a good idea to stop the medication but he does seem to be going from one expteme to the other. To me it sounds like mania only going by the way my mother used to behave. I am not an expert but I am sure some of the more experienced on this site may be able to give you more advice. It may seem odd me saying this as I stopped taking prozac as I am afraid of all the side effects but he needs to go see the dr. Good luck. If I could find something that would help me not feel the way I do with no side effects I would gladly take it.
