how much potassium are you taking?

maybe something is getting out of balance?

I wonder if taking magnesium would help with the spasms, or a calcium/magnesium blend.

[What is magnesium?

Magnesium is usually referred to as a "macromineral," which means that our food must provide us with hundreds of milligrams of magnesium every day. (The other macrominerals that all humans must get from food are calcium, phosphorus, sodium:nutrient, potassium, and chloride).

Inside our bodies, magnesium is found mostly in our bones (60-65%), but also in our muscles (25%), and in other cell types and body fluids. Like all minerals, magnesium cannot be made in our body and must therefore be plentiful in our diet in order for us to remain healthy.

Magnesium is sometimes regarded as a "smoothie" mineral, since it has the ability to relax our muscles. Our nerves also depend upon magnesium to avoid becoming overexcited, and this aspect of magnesium links this mineral to maintenance of healthy blood pressure. ]
