Thanks somedaysoon. I have never had any root canals, fillings or amalgams of such. My mercury poisoning came from eating excess cans of tuna fish. My mental symptoms started originally in late 2002, then late 2003 came my ulcerative colitis. However, I did 2 hair analysis, 1 in Sept of 2005 showed mercury, then another in January 2006, showed no mercury. I did a heavy metal cleanse kit off the shelf from whole foods by Renew Life. Anyways, my symptoms are still here along with the ulcerative colitis thus making the option of having candida a high possibility, almost sure. Anyways, there are candida cleanse kits that you can purchase as well. This hollistic guy is making something for me which im going to go pick up right now. ill find out more exactly what it is. - Mike
