I must admit I underestimated the strength of the methylation cycle therapy. Following a colon and Liver cleanse I have been taking methylB12, P5P, Zinc and Vit E and on occasion Tumeric. I've detoxed an awful lot. Unfortunately, I have a feeling that I drew out a bit of heavy metal, perhaps mercury, out of my PNS tissues. It feels as if it hasn't cleared however as I'm getting tingling sensations, muscle twitching etc. What is a good chleating substance that I should take to adequately clear this?
