You need magnesium. Take metagenics brand mag glycinate and/or source naturals mag malate. Each tab is about 100mg; build up to 8 per day (2 at each meal and 2 at bedtime).
Build over several days as you can get diarrhea if you take too much too fast. It WILL go away.
I have heard of taking magnesium (2 @ 400 mg per day), however did not know about the different types. I have ordered the source naturals mag malate online and am going to try this type.
Thank you for the info.
