My previous remedies have been ineffective. Those include doctor recommended "Just drink more water", magnesium (from Calm powder), electrolytes (sodium, potassium, and magnesium mixture). I am still experimenting but so far, the potassium aspartate plus Calm (magnesium carbonate) is working.

Potassium can kill you, it is what they use in lethal injections.

I have taking small amounts (1/8 teaspoon in a glass of water) of potassium aspartate every evening, for the purpose of preventing nocturnal muscle cramps.
