On the tonight show last night this actor talked about using lead based paint as body paint early on in his career and ending up with vibration feelings, tremors which where diagnosed as lead poisoning.
I have had vibration feelings off and on for the last few years now; I find two things that work. One is Benfotiamine (special kind of thiamin) and TLC (a lead chelator) Actually if I take two or even three doses of TLC per day during these flare ups I get no further vibration issues.
The SCIO showed me borderline MS with some Myelin Sheath damage, I believe Mercury causes this and when Lead makes it back into the blood may aggravate these damaged myelin sheaths and cause this vibration feeling.
Either way, it has diminished since the metal detox and only shows up once in a while now when I step back my TLC usage.
