If you were that low, then you may have a substantial anemia too. When your body replenishes B12 in the tissues, the bone marrow takes alot to make red blood cells...and these take potassium also out of the blood.
So some people become low in potassium... Eat potassium rich foods, and perhaps get tested at the doctor's..to see if you are low. Then your doctor can give you an RX for a potassium supplement. He would determine your dose based on the blood work.
