I've not done anything since finding PC, so hope it works for you too. My favourite distraction used to be trying to draw a picture using both my right hand and left hand at the same time. I'd start with a simple outline and draw both sides simultaneously, I'm right handed so I'd have to slow my right hand down and concentrating on that stopped my left hand wobbling. It was just about the most frustrating and pointless thing I've ever done, but that was kind of the point. Do you have any distractions?
