Good questions Rick

I think once you start experiencing dramatic symptoms such as freezing, on/offs it is the domino effect. We forget how to relax and enter a fright/flight response. If I am out in public and I start becoming symptomatic my immediate response is.......like I am so out of here, I just want to go home tear off these cloths, put something comfortable on and get into the most comfortable position possible. Fear seems to be part of that. Fear equals big time stress. Our defenses get worn down. The inconstancies of pd can drive you nuts alone. I have some comments on freezing but I am off to bed. Catch up later.
