I've not had this experience myself. But I thought I would just leave a brief reply letting you know I read your post. I seem to recall having been put on risperadal at one point way back probably 20 years ago or so when I first became involved with the mental health services system where I live. However I didn't stay on it (or any other med they put me on) long enough for it to become a problem. I'm sorry you had such a devastating experience. Hopefully coming here to PC is of some comfort & support.
