for what it's worth i think you flushed too many electrolytes out of your system with the Liver Flush ( Epsom Salts can be harsh like that) and this is why you got thirsty.i've also had this problem the past few days , it does get a little better when i consume extra Sea Salt .
have you had any luck with your adrenal fatigue symptoms (or whichever diagnosis you decided on) , im giving isocort a try hopefully that will improve things.
