I've been on it for almost two years. It has really helped me stay stable.

I do have akathisia on it as well as tardive dyskinesia but I'm on the lowest dose and take Artane and Vitamin E to reduce those effects. I take it in the morning because it doesn't make me drowsy. I've been on Lamictal with Zyoprexa and Depakote with Geodon, and this has been the best experience yet.

People's experiences vary though.
