They can control it but are not aware it is happening unless someone tells them? easy child/difficult child is on Resperdal. His leg will bounce up and down rapidly while he is sitting watching TV, reading, having a conversation, or eating. It is very annoying to the people around him. He is trying to get permission to return to work and I am afraid that this disruptive behavior will get in the way of that goal. Is it a tick? Shoud we ask the doctor about it? Is there medication that reduces these types of behavioral responces to Resperdal use?
