I've been on my meds that made me feel flat, and it's a crappy feeling. Although I'm somebody who hates med changes, it's done me good in the long run to either add, take away, or lower the dose of certain meds. Although I sometimes get flatness from depression in itself, but for most part, my med changes at least allow me to have a personality now. I felt a lot better, in the sense of not having that chronic "flat" feeling....so just some things to consider. Good luck!
