I had my amlgams out nearly 8mths ago and i get ups and downs and the real downs are when my candida has flared up, ie, brain fog, lethargy, feeling drunk, unfunctional, depressed, i can only put it down to candida as im doing everything right, except eating too many gluten free grains.
It takes alot to keep the candida under control, sometimes even one mistake can produce horrible results.
Its wise before any amalgam removal that you are strict, 100% on the diet, otherwise you can end up worse after removal. Hope this helps a bit.
