yes, but I've had mercury since i was about 5 so never really gotta chance to develop any personality. I always did know that I had a good personality however over the years it has shone through all the mercury. What I've found with chelation, specifically alpha lipoic acid, is my perception of the world is becoming much more positive and realistic, which has allowed my personallity to develop and shine through more than ever. Its all the mercury, don't let it beat you!
