I have had tis muscle twitching problem for a long time. It seems to be worse when I am tired, don't sleep well or have some flare up of symptoms related to intestinal dysbiosis. I have come to believe that toxins are released in to the blood stream from Bad bacteria in the gut, or if you prefer, candida. My legs, eyelids and various other muscles twitch and it feels as though something is terribly wrong. I have tried to live with it, but I know it is another reason to believe that this illness is frustratihg and difficult to understand and control. I wish I could offer more help. I have tried magnesium supplementation but any meaningful amount seems to cause diarrhea. I do believe if Dysbiosis can be corrected then these muscle twitching problems will dissapear. Dysbiosis, as we all have come to understand, is not easilly cured. Hang in there. We are all in the same boat.
