Oh yeah I totally relate. I was on risperdal and depakote for four or five months after my psychotic break last year. While the medications worked and snapped me out of it, I felt like a complete zombie. It was horrible. No emotion, affect, nothing. It felt like my whole personality was wiped out.
I switched doctors and they took me off of those meds. I went on a small dose of lamictal and imipramine and slowly my personality came back. It did take a little while.
