I suppose there is some overlap between DMSA treatment and the lignisul MSM I mentioned-
Though the insomnia periods I experienced on a frequent basis had some say in my choices during researching chelation. The cutler protocol reccommends waking every 4 hours or so for vit C dosage, and I have experience doing that from testing for insulin pump therapy.
I don't know quite where to find data to compare microdosing nutritonal approaches with sauna treatment, compared to chelations.
I wonder though, since lgnisul MSM is so closely related to DMSA, does that rule out the crossing of the treatment to the BBB?
Yes, I experienced the problems you mention with your friend sweating poorly- up to two years ago I had the same, sweating like a pig at all the wrong times. The NB approach can be a puzzle in and of itself, but I'm thankful for what has been achieved so far..
And the feedback and experiences of folk such as yourself, Joe.
