Re: why is nothing coming out?
I would say a lot is coming out; anger can be a detox too, I have seen in a few cases, especially children.
My own detox was a 2-3 months hell of infections, fevers and digestion problems; this comes out different for each individual; I didnt have bromide headache until lately, three years into Iodine
In your case the imbalance may lay in the emotional layer of the body, and I agree with JT; take a break if its bad.
Another option is homeopathy; remedies like nux vomica comes to my mind; especially if you have digestion problems and are using coffee or other stimulants to cope with stress. There are many other remedies, and if you see a homeopath he or she can prescribe a remedy that may help.
you mention depression; is there a bipolar tendency in you or your family? in that case I would consider supplementing with lithium orotate.
When it comes to magnesium, dont give it up just yet; this has for me been the most difficult supplement to make work; I would try magnesium malate or citrate; 400-600 mg daily. But vit B6 are needed for magnesium uptake, so add vit B complex as the B`s work together.
A little boron will also help for the magnesium-calcium balance. Very important if you have much stress in your life.
