I feel your frustration PP. I'm wondering can you be open to the possibility that the stress state we are in is constant? That something internal is causing us to be frozen in fight or flight even if there is no reason for it?
Lam's site has a lot of good information. Though this is the big thing he doesn't consider. According to Lam if a patient is not better, it's because they messed up the protocol in some way or they haven't given it enough time. I think it's a mistake to not consider this other possibility.
