Hi...my symptoms are these: the worst is the belching. Everyday for 5 months all the time even when I drink water. It's unexplainable. Mild nausea on and off. Trouble gaining weight. Terrible muscle twitching. Arms and hands often fall asleep at night for no reason. Subtle inner vibrations. Dr said this can all be a magnesium deficiency which may be tied to parasites as well as the burping. I've also noticed a few times tons of tiny dark flecks in my stool (actually just on the tissue...looks like pepper)?
