H.S.
My husband is bi-polar (hypomanic) and has been on Stavzor, www.stavzor.com, which has seemed to calm him down and help him make more reasonable decisions, not quite so moody, impulsive and selfish. Just another option to ask the doctor about if you don't like what your son is currently on.
My problem is getting him to take the meds...he seems to like to always be on a 'high' w/o his meds, which makes life for the rest of us a living hell...won't sleep, party animal, makes costly impulsive decisions, etc...
