Very much with mood stability. Psychosis has never been nearly the problem that rapid cycling and severe mixed episodes were. Psychosis was manageable with med changes. No mood stabilizer ever really helped me much with the mixed episodes and I tried pretty much all of them; I think all but tegretol and that was because trileptal was a disaster. I went on a bunch of APs but some didn't work, some had EPS issues, some I was allergic to and that left Seroquel which I eventually was taking 1500 mg of XR. That wasn't working so that left clozapine and while I've had occasional psychosis that was easily handled and some small mood episodes I've had nothing like what I used to live with all the time. It's totally worth the blood tests to not have constant mixed episodes, and I'm pretty happy with the lack of psychosis too.
