Spoke to my Doc and he said give it a try. So I did and it made my headaches worse. As soon as I stopped taking the Magnesium my headaches went back to my baseline. Weird, I guess I wasn’t deficient in magnesium. I’ll be curious to ask my Doc at my next visit why it made my headaches worse.
On a side note, my wife who is not a chronic migraine suffer had the same side effect when she took magnesium citrate. In any case, it was worth the trial in case it worked.
