Yes Magnesium is great.
That is a brilliant link you posted, bg123.

Actually I thought I could not help,but maybe if I write what I did to get myself feeling better since my episode the other night,

straight away I took a few drops of rescue remedy,

took a few sips of water,but held it in my mouth and under my tongue for a while before swallowing.
It goes directly to where it's needed most this way,

I took a pinch of himalayan rock salt onto my tongue,

I drank half small cup of rice milk with some cayenne pepper in it.(for a few reasons 1.to try &get some heat into my body,
2.A practitioner told me it's good to treat shock.and my body felt in some kind of shock.freezing & shaking.

I ate an apple,some chopped raw pepper and some celery,
and about 3 handfulls of pumpkin seeds,these are really calming nourishing food(also high in magnesium & zinc)
it was really hard to chew though because my face felt all numb.

I massaged my face neck and inside arms with natural progesterone cream and this is when I started to feel somewhat normal.
This cream is also suitable & recommended for men.

I also took about a quater teaspoon of blackstrapp molasses
(maybe not for you said you doing the candida cleanse)but I took it because I thought it was hypoglycaemia that was happening.

Also it's important,if you can to breathe through your nose & not your mouth, this is much better for you.

Then after half an hour I made a strong half cup of camomile tea and when I finally fell asleep I felt much better.
