HI TW, you could always give ALA a go on its own for a while without DMSA, if the DMSA is too strong a medication for your system. AT least ALA is an antioxidant.

Andy mentions that cilantro can apparently detox brain mercury, but he's not sure of the right way to advise using it as yet to ensure safety....so it may still be a risk, even at this point. That would be up to you.

Other than that, if it's all too much, I guess all you can do is eat healthy and possibly try and sweat some of this out via the pores (hot baths with epsom salts or sea salt and baking soda etc). However, not sure if that helps get rid of brain mercury. Im' pretty sure that it's quite touch to get out and needs a strong chelating agent for that and ALA and cilantro are the ones that seem to be mentioned as being able to do it.
