Re: Mercury and polydipsia/ renal failure - plea for help
I suggest you don't completely trust metals tests. They are not known for their reliability. I would be careful believing what most doctors say too since there seems to be widespread ignorance on the topic of metals and chelation.
The first key question is: Do you have or have you ever had silver fillings? If you have any now, you will need to replace them before you begin chelating.
Second question is: Any idea what metal you may have been exposed to? It makes a big difference for what protocol you follow for chelation. Mercury and lead are the two most common, but there are others too.
Like UchihaMadara wrote, you definitely need to use the ALA systematically and frequently in order for it to work. Taking it every 3 hours, including waking your self up at least once in the middle of the night to take it again. This will keep the effect going long enough for it to do any good. If you have silver fillings, you should wait until a few months after you replace them to begin using ALA.
This is an overly simplified description of Cutler's Protocol. If you are going to use ALA, you should use the protocol to do it. Cutler recommends you use DMSA too, but there are people who only use ALA.
Definitely don't go into chelation without finding out as much as you can about how to chelate. It's not 100% risk-free and a little knowledge will help you understand how to minimize possible risks.
