I took risperdal involuntary for a month at 18, 15mg, it's the only drug that I refused to take again. I felt like a zombie. It took so much of my energy to walk, eat, and talk. My family couldn't understand me when they came to visit me because my speech was extremely slurred. I also lost 40 pounds and that's the only reason why I was taken off, because it became a danger to my health, physically. I don't remember twitching, but then again I slept most of the time.

I suggest you only take for medical reasons there are other drugs to experiment/have fun with, this is definitely not one.

Although it is good for paranoia, that's not why I took it though, but I must admit no thoughts whatsoever was getting through.

Take care, I hope you find the best med/s for you.
