Lotus, magnesium does help fibro. I take malic acid/magnesium supplements. There is a link about these in Fibro 101. This has helped quite a few on this forum. So does vitamin D3, since many are deficient in that too.
I can't have things with MSG in them. I get very dizzy and my heart races. There is no reason to use that stuff anyway. I prepare my foods fresh and rarely use prepackaged products, too.
