Don't take an SSRI. A much better idea is to take licorice root(unless you have high blood pressure). I drink a cup or two of licorice root tea most days.

JPL, have you tried using detox teas? The Triple Leaf Detox Tea is my favorite detox tea. One important thing is to make sure you don't get constipated while chelating, as this can make you feel very horrible.
