Do you think it's necessary to take an antipsychotic or can a good mood stabilizer do the job of keeping you stable...

I'm on Latuda and still weaning off of Seroquel. I don't like the side effect of feeling restless and I can't sit still. I think it's because of the Seroquel on top of Latuda - I've been on Latuda before and never had the problem. However, can a person do well with just a mood stabilizer and no antipsychotic med?
