mercury poisoned-just got test back! ?'s

After doing a 6 hour urine test induced by vitamin c and dmps, I finally got my results from my doc.
it was elevated twice the acceptable level and the number was 8 something.

My question is this. Is that high? I have several symptoms such as brain fog, fatigue, shakiness, heart palpitations, nausea, and a host of others that all come and go.

Anyone out there know of heart disturbances from mercury? Am I alone? Is this really the cause?
Is my number high enough? Does the number matter or does each body react at diff levels?

I am at a wellness center with a doc that was a med doc for 20 some years and went searching for more answers and not just meds. He has been practicing chelation for 20 years since. I like him and basically feel safe just can't trust anyone after my four years of run around with the general medical community trying to find the root problem.

I have started a program of chelation with vit C/glutithione/Saunas and ionic foot baths. He is supporting me with vit c powder, selenium, amino acids, chlorella, barley powder and b12 as I am a ovo- vegetarian. Is this a good plan? I am also eating a healthy Diet with lots of fresh fruits and veggies-no sugar-and juicing cilantro.

Am I on a good track?
