Thanks for the post. I don't know Julie A's history. I don't recall ever hearing that she had a mercury problem.
She seems overweight so I would not be surprised at joint problems. Since she said she just had knee replacement surgery maybe that was involved in some of her physical discomfort when you saw her.
If you have a mercury problem you are not going to want to discuss those symptoms in public. There will always be mood/psych issues.
Do you expect such a person to say I had really bad PMS where I was moody and driving my loved ones nuts until I got adrenal support and detox?
They have recurrent candida problems, constipation, brain fog, etc. A professional will not want to discuss that unless it was public knowledge that there was really devastating health problems and obvious gains--for example Dr Mark Hyman.
