I do not have CFS/ME but I seem to get recurrent episodes of Refeeding Syndrome after a time of decreased calorie consumption. I experience extreme Hypophosphatemia and Hypokalemia and become completely weak and debilitated and the more I eat the weaker I become. I have seen several posts of CFS/ME sufferers having Refeeding Syndrome issues. My question is, how do you know you have it? Who diagnosed you? How are CFS/ME related to this? Also does anyone know of a Dr. in Illinois who has successfully treated it? I am not getting any help from the medical community and I'm wasting away. Thank you and God bless.
