I vomit within 30min of taking even the most minute amount of magnesium supplements. Multivitamins seem to be fine but magnesium alone in anything but a trace amount causes an allergic reaction. Are you saying that if I can put up with vomitting daily for a week or two then it might go away? I have a magnesium deficiency (often goes hand in hand with an allergy) and really need to fix this. Eventually I hope to see a specialist about it.
