I have been taking olanzapine for over a decade and tapered from 20 mg to 1.5mg. I currently sleep 7 to 8 hours on 1.5mg but desire to be off completely. There are still a lot of side effects on that minimum dosage. When I’m off I sleep 5 hours the first night, 4 the second, and 0 the third. Please recommend something to help me sleep normally without this poison.
