My kidney function is good. I'm healthy other than the SNF/Erythromelagia. I take no acid blockers - H2 or PPIs. I've been on Mag Glycinate and Mag Citrate 400 mg per day for some time to help out with constipation from my Gralise pain med. Interestingly while on Mag Glycinate my Mag levels tested perfect. So maybe I run low normally - whatever normal is for me. I've tried Mag Oxide but know it's a waste of my time.

I've tried the Magnesium Sulfate Cream by Kirkman. It did nothing for me.

I've read the abstract from Dr. Cohen's paper but don't have the full text. Can someone get that for me? Intravenous Mag sounds impractical, but it sounds like some in his paper used oral Mag?

Since I am throwing darts, sure I can ask about Cyproheptadine. Thanks for the idea. I will ask about an Rx.

My doc thinks overdosing on Mag orally would be tough to do. But I do know the signs, just in case. And no I don't have diarrhea from the levels I am on. Still I'd like to jack the dose higher to see.

Don't know if this answered all your questions, but thanks for the ideas.
