@ ipj:
Did you have any other symptoms caused by that magnesium deficiency?? Would be so interesting to hear, if you also had cramps in your legs or so. I always wonder, if those cramps HAVE TO BE THERE, if you have a lack of magnesium or if it even can be shown alone by all the other symptoms (nervousness, heart palps, dizzyness, headaches, etc.)...
Best wishes
