Hello. Now, whatever you do, just hang in there. One day at a time! It's going to come out in the wash.
I am not a medical practitioner, but I can tell you about the magnesium we take here in our household, which is quite something! It is a fine powder that you mix with a bit of hot water, then it fizzes, then you stir it till it is perfectly clear - there is no residue - then you dilute it as you wish and drink like a tea. In other words, it is totally digestible.
It is called "Natural Calm" and manufactured by Peter Gillham's Natural Vitality.
www.petergillham.com Contains Mg Citrate, stevia and natural orange flavor. A daily serving is 615 mg but you may need more.
I am not telling you not to take capsules of Mg or Zinc, only that certain preparations are more easily digested than others. For me, liquid nutrients always worked better, for some reason.
The label on Natural Calm will explain when you have had your optimum dosage.
In any case, we here are all thinking of you and know that you will get as healthy as you want - you just have to get thru these crises times (and you will).
