My husband has a manic disorder and frontal lobe head injury. He does not have ups and downs....only up and up and up, until he lost our business, our home everything. He was put on lithium and it was working well, however he did not like feeling normal and they added Welbrutin. This gives him the high he likes and is breaking over the top into a manic state. What is a drug that will help him with the mania, yet not make him feel like as he says a Zombie.
