From what I have read it is an electrolyte imbalance caused, in part, due to the amount of water we drink. I take a multi vitamin, Atkins EFA, Potassium, and CO Q10 supplements. Seems to be working for me. Try your vitamin and see how you do, you may need different stuff or maybe up your veggie count of carbs a bit. Good luck, maybe someone more informed may stop by with better info.
