No, I have not been tested for heavy metals... How would one get a buildup of them? I don't drink anything but water, and only bottled water at that, by the way. As of 6 days ago, I now have vertigo too. It came on all of a sudden and was like someone was violently shaking my head, with vomiting and nausea. As of 8 days ago my dizziness has doubled from what it has been the last 4 months. I see the neurologist the day after tomorrow, and am at a loss for what to say or ask or tests to ask for.
