Regarding your itchiness. I had posted a similar complaint awhile back and GINAGIRL replied with this:
"Itchy skin, magnesium balance; add boron to your regimen.
Internally, externally; a supplement that really helps.
Maybe what you are missing."
I saw your post on inquiring about boron but did not reply because I did not know how to but I do take it. I take around 9mg of Tetra-Boron. I also think you just need to follow your regime and wait patiently for it to work. It can take 6mos to 1 year to become sufficient and I think that is when you will get a lot of your answers. By the way since adding Boran---no more itching.
