Jinx,

I would not chelate at all if amalgam fillings are present. Good protein diet would do you more good than chelation at this point. I would personally recommend Algin, as it will be absorbing the floating mercury, thus making you feel better. I would include these in my diet with the fillings still in: Algin, vit c, e, b-complex, magnesium, calcium, zinc, cod liver oil, and milk thirstle.
Mercury likes to hide and one of the simptoms you get as the result is that mercury is not your problem. However, you mentioned about swallowing a thermometer and having mercury fillings, so you are mercury poisoned. Don't let mercury trick you that it's not the thing to blame. You will have to get all fillings removed, drilled pulled or whatever. You will never truly have brain power if you have brain mercury. I am currently having great results with chelation. But I had to get my mercury filling drilled and then the same teeth pulled due to damage from drilling. What am trying to say is that you should focus on finding a way to get all metal fillings out and taking supplements listed above. No God can help you, but only you can.
