To help him stop moving and talking in his sleep. He took about 25 mg. for about one month and then stopped taking it. He's been very angry and has been verbally abusive. He stopped speaking to me for 3 days and then apologized and then one day later decided to end our very short marriage. Could this have anything to do with him stopping the quetiapine? I'm very worried about his mental state. I've tried reaching out to his family but they do not believe in taking medicine.
