Ditto on the cramps. When our sugars are high we pee out all our minerals. I had hideous cramps before I was diagnosed, and I still have to be careful. I take calcium, magnesium and use salt that is half potassium.
Mine were in my thighs, mostly, but sometimes my feet and calves, too. I thought they were going to snap my bones they were so strong and so very painful. Yow.
Someone needs to add these cramps to the list of possible symptoms of undiagnosed diabetes.
