I don't think you can blame Seroquel for the violent irritability. It should be just the opposite. You said you were taking 75 mg. From what I've read, the minimum therapeutic dose is 200 mg. Anyway, you said you are still having violent urges even after you quit taking it. It's not really a very good idea to stop taking medications without telling your doctor.

You say that it is becoming more unmanageable on your own with meds. Since you stopped the Seroquel, the only med you are taking is Prozac. That's just an antidepressant. You can't expect it to do anything for violent or psychotic behavior.

How to talk to your doctor? Just write down everything you have said here and repeat it to him. Or you can just let him read it. Have you tried finding a therapist? I think that would help.

Anyway, I'm sorry you are struggling, and I really hope you can get it under control.
