Which chelators do you need to combine?

Hi,
I'm new to chelating and think I'm doing it wrong. I've been taking lots of Vitamin C and using ozone and my nerves feel shot. Always trembling and feeling numbness in extremities.

I guess I need to combine different types of chelators?

I think I'm not mixing them with a extracelluar chelator to prevent reabsorbtion and am detoxing too quickly.

From the little research I've done:

1. Vitamin C is gets inside the cells?

2. Alpha Lipoic Acid gets inside the cells?

3. Cilantro gets inside the cells?

4. EDTA?

5. Ozone/Oxygen Therapy?

6. Chlorella is for outside the cells?

7. DMSA or DMPS is for outside?

8. Iodine/Iodide?

Anymore? I was thinking of combining Cilantro, Chlorella, Ozone, Lugol's Iodine, and Vitamin C.
