I concur with JT
brown urine is bromide coming out
and the wrenching of the back could be kidneys struggling with the detox
are you taking breaks on the Iodine at all?
so how many drops of SSKI per day????
you might be doing too much
I did a gram dose two years ago and put my back out
make sure you are taking as much magnesium as you can
and you might try either buying Pulverxx or buying the individual herbs: Chanca Piedra, Boldo and H**** I am forgetting that one right now
Also could be worth getting with someone who does really good craniosacral work. I can help you with that if you are willing to share your zip code with me. I have helped several clients with dizzy and vertigo stuff recently with Cranial work.
