Gupta process.
I am sceptical too. I don't think this is a straightforward psychological illness. But after having PTSD where loads of physical stuff was rooted in the trauma, and having treatment that made my body relive the event and then process it appropriately, I am very much aware that the brain is not simple.
I do believe that part of my brain could be making my system run on 'high alert' at inappropriate times, which could be leading to exhaustion. And the exercise intolerance could be (?) because of adrenaline stored in the muscles being used because my normal adrenal function is shot to pieces.
Tests have not shown that I have weird cortisol levels though. I don't know. The free Gupta videos on YouTube seem okay, and I'd rather pay £117 for DVDs I can keep and use over and over at home than £400 for the Lightning Process which would involve going out to appointments.
Am considering it, but probably won't do anything until I've had the treatment for intracranial hypertension...lumbar puncture followed by ballooning a vein which has narrowed. Complicated, slightly risky and somewhat experimental stuff, but I feel lucky to have any options at all, really.
