Do you know if your husband is being given dexamethasone as one of his anti-nausea meds? It's a steroid and I can tell you from experience that it can make the person crazy as a hoot-owl. Feelings of euphoria, non-stop talking, and some aggression. Sometimes there is a big crash after the med. is stopped.
