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The flow which helps me is the liver flow (unpublished) but every practitioner knows.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.
