you're welcome.

Yeah, would be great if Andy would get on. Perhaps you could copy and paste what you've told me here over there and see what response you get? andy may even reply to it too.

If you can get hold of some DMSA for your brother, he could start taking small doses of it, as long as he does it every 4 hours (which is the most important aspect). Not fun to wake up during the night, but it is necessary and worth it. If he can do that for at least 3 days on, and 3 days (or more) off and just keep repeating this cycle, he may find his symptoms become a bit more tolerable and hopefully will start noticing some positive improvements.

This helped me a great deal.

I have used it after getting a very bad backfire effect from another protocol/product I used, which mobilised mercury everywhere and made me horribly sick. And getting on the DMSA every 4 hour routine actually helped make things stable again.

In the end, I realised it was the only way I was able to chelate the mercury without going out of my mind.
