I'm obviously no doctor, but Lamictal helped me out a lot anger/agitation wise, same with Seroquel. THOUGH, going off Seroquel made me severely pissed off, like really bad, so that's how I know it was working for me.

Sorry your doctor never called back. No advice for that besides physically going into the office when you get back from vacation. But if your doctor is notorious for not responding, then you should consider finding a new doctor.
