It would be good to call your psychiatrist and tell this story you wrote. Maybe do consider the ER.

My response to moodstabilizers, like Lithium and anticonvulsants, is not full either, though I do believe Lamictal is helpful for depression (but not my manias) and Tegretol XR got rid of musical hallucinations I once had for some months in the past. I have always needed at least one antipsychotic.Antipsychotics work best at preventing and extinguishing my manias. Seroquel XR is even helpful for my mixed episodes.
