I used to jut out my chin like a head jerk and to stop that , I started to tap my chin, then to stop that, I started to clench my fists, then to stop that I started to close my eyes shut because I looked like I was about to buck up and fight someone all the time. But and now I keep my eyes open and have no more secondaries that I know of. I do tap, but thats deliberate not involuntary. It was a journey lol.
