It has now been seven or eight hours since the single spin. Have done better than usual all afternnon with only one period of "Off" at a small local art gallery. Other people milling about, etc and freezing was only minor. It is now 7:00 PM and I feel over-medicated with some dyskinesia.
I have been doing some research and it really may be that this would help more than just freezing. If you have a desk chair, try it just to the point of nausea. It isn't necessary to be sick but the same chemical changes involved in the symptom relief also trigger motion sickness. Darned side effects everywhere!
