Yes, he says so, but it didn’t work for me and that is the only reason I can think of as most of the techniques in all of these programs are for damping down the sympathetic response.
Oh yes, I forgot, you mentioned this before. I would think it's something else, but maybe you're right. If I remember you said you really did commit to the program right? Do you feel like when you did the exercises, you really believed that the pain/symptoms were false brain reactions, or were you more just saying the words? I noticed a shift a few days ago where it finally clicked for me that the symptoms are false brain messages, and I feel like I dissociated them for the first time and the words I'm saying I actually believe now.
