I don't know why people into the Mercury / Candida thing believes that everyone has this problem.

Your symotoms are purely those of a stress/anxiety disorder. You might have mercury poisoning, OR NOT. Those things just happen. If you start wioth the mercury thing get ready to devote your life to a never curing condition and spending millions.

WIth those symptoms, you just can't tell what you have and the usual thing is ANXIETY/STRESS or even getting older.
