I am finding Jin Shin will eliminate my worst symptoms. Jin Shin is worldwide. The book about it is
The Touch of Healing by Alice Burmeister. And no I have no financial or other interest in this.
The flow which helps me is the liver flow (unpublished) but every practitioner knows. if you wish I can publish here... Others may find other flows of use. this is the site to find a practitioner near you
https://www.jsjinc.net/Pick one with the most experience. usually practitioners offer 'self-help' seminars which will enable you to use the flows on your own with a little training...
I have tried almost everything in the last 3 years and this is the single more helpful item. I don't know that it solves the exposure problem...but it deals effectively with the aftermath of exposure for me.
