If you are suffering from any chronic health problem, try looking in your mouth for a possible cause. If you have any metal in your mouth, whatsoever, consider finding a dentist who can remove it safely and replace the material with a safe composite containing no metal. Possible sources for metal include fillings, crowns, root canals, bridge work, partials, and implants.
If you are suffering from any G.I. tract problems, try considering that you are a host to parasites and take an herbal remedy to eliminate as many as possible. Black walnut hull liquid extract is one example of a remedy to kill certain parasites.
