I suggest you try the Cutler Protocol. Make sure you use DMSA since it works on more than one metal. It's expensive, but it would likely give you the most bang for your buck. Other chelators are mostly good for either mercury or lead. I'm a bit confused about ALA though and whether it's only good for mercury or if it works for other metals too.
Any idea where all those metals came from? You really need to find out and protect yourself from them.
My health problems improved a lot after I chelated for a while. It's likely that it would help you too; especially if your metals are so high.
