I think that you should try the aripiprazole as it has a pretty different mechanism of action to chlorpromazine/quetiapine (chlorpromazine is a dopamine-2 antagonist and quetiapine is a serotonin-dopamine antagonist, whereas aripiprazole is a doapmine-2 partial agonist), and aripiprazole does good work on negative symptoms. Will he keep you on the chlorpromazine? As aripiprazole can cause activation and insomnia.
