I have used several things to recover. A Neural Rewiring Program, Tapping and TMS work. I would guess that I am about at 75% recovered. What is remaining is some strongly held food allergy symptoms that are basically conditioned responses. So I am still recovering and strive for 100% eventually. My symptoms from food allergies were what I had the most fear of and the things that scare us, also help to make those reactions stronger (deeply rooted neural networks in our brains). But I did not know all of that at the time.
The Neural Rewiring program I used was something that I still do, as it helps me so much and I love it. It is called DNRS (Dynamic Neural Retraining System.) Many people that do it, can obtain full recovery within 6 months to 1 year. Then some take much longer, but just like TMS, some people who do DNRS experience Book cures too and get well really quickly.
DNRS teaches you how to stop the fight/flight/freeze stress response that keeps our trauma loops going. It uses NLP (neuro-linguistic programing), self guided visualizations, CBT, and many other things to literally rewire the over protective stress response of the subconscious and limbic brain that are causing the reactions in the first place. You can check it out at dnrsystem.com
Tapping really helped me too. I hired a Faster EFT practitioner to do private Skype sessions and we went through some of my past traumas and cleared them out, which gave me some relief of my physical symptoms.......(pretty cool)
Then I found out about TMS just this summer......DNRS does not call it TMS, they call it a Limbic System Injury. (Same thing). There are many things you can do to recover. And something that will help you tremendously is to practice TRUE INDIFFERENCE. Which is to live your life like the symptoms are not happening. The more you fight it or let it frustrate you, the more you fuel it. Acceptance, and not fighting it, will help. When we do this time after time, the brain catches on and realizes that it does not need to distract us with the symptoms anymore.
Your symptoms are coming from the unconscious/subconscious/limbic part of your brain, so when the Conscious brain says........"oh this is bad, or UGH, when will this ever stop" this makes things worse. We have the ability, with our conscious brain to interrupt that stress response, instead of feeding it.
