Well I did a urine test, and the test colour changed almost immediately to the mercury indicator, and it all makes sense as this came on weeks after having the huge mercury fillings. So will be finding somewhere I can afford this week to have them removed.
Thankfully Dr Lams protocol already contains most of the de-tox supplements for the mercury...after looking more and more into this it really does seem possible that mercury poisoning is the root cause to my AF.
