Hi Colin, well nobody can say you haven't given it a very good go and it does not seem likely that mercury is involved....unless the pills you're taking are duds.

<img src="/ubbthreads/images/graemlins/wink.gif" alt="" /> which I cannot imagine they are. Do you get any effects when using any sulfur supplements? E.g. garlic? MSM etc.

Have you thought of trying cilantro?

Have you treated candida? (can cause many symptoms confused with mercury)...

Otherwise, I'm mystified.
