I had the zombie thing with Prozac and another SSRI. Seen others react the same. Resisted getting off it though for some strange reason - an escape from reality. Almost lost my job cause of how i acted on it. I'm dumber than I used to be now - couldn't do math when I was on it - now math is confusing, used to be my strength. Also had hallucinations and throught I could read minds, like ESP, when I was taking it. Other times was lethargic or couldn't speak, like my body woudn't react to my mind.
