I ended up in the er yesterday due to abdominal pain and turns out im extremely constipated. xrays showed that intestines almost full and was told to drink magnesium citrate. I was told to drink 1/3 bottle at a time. After first dose had bad cramping and some diarrhea (some form to it still). After the second and third dose its yellow and like water. Could I have expelled everything after the first dose or is it possible some is lodged?
