Like Eric said, the amount of time needed to chelate heavy metals is important.Having just five IV's over a course of three months maybe not enough time to remove the heavy metals from your body. A longer duration of IV chelating maybe required, but the cost as your well aware is overwhelming. You may have a leaky gut issue as well. And it's quite possible that your issue may not be heavy metals but candida which mimic's all the symptoms of mercury posioning. It's difficult to say for sure what's going on here.
