I too am about to have Amalgams removed from my mouth. I have been plagued with "fibro" type symptoms. Within in one day of having my root canal tooth pulled, I noticed a significant improvement with some of my most horrific symptoms.
I am planning to have a Vitamin C intravenous drip done before having the mercury filling removed. Within 24 hours of having the mercury filling removed you should continue the chelation therapy. this was told to me by the dentist who removed the root canal.
Look for a GOOD holistic dentist who will be able to guide you to a nautropath or holistic M.D. to work with during the Amalgams removal.
