Many people do eventually recover. You need to keep in mind though that many people have been poisoned by their mercury fillings for more than 20 years, so to expect to become well in just a few months is not reasonable. My theory is that due to mercury toxicity, the body's natural detoxification channels get clogged, so people become toxic as well with the other toxins present in low levels that it can normally eliminate. Getting all of these toxins down to low levels in the body can take plenty of time. Some of these toxins such as lead end up getting stored in the bones, and it can take a long time for enough bone turnover to clear these out.
