well for me I know taking Zyprexa gave me a mood disorder, at least a worse disorder. Before I was just kind of unstable but I never had any of this emptiness business I experience now. And I know it was the meds because that is why I stopped them to begin with, it gave me the same sensation just a little more intense. It never went away. I don't feel emotions properly anymore.
I'm sure meds can cause ALL KIND of problems that are just being blamed on the illnesses themselves.
