Has anyone been given medicine called k-phos?

Kali phosphoricum. This is a homeopathic medicine, sometimes called a "cell salt" because it's actually a nutrient found in body cells. As a homeopathic remedy, it can help people who have mental fatigue, irritability, restlessness, startling from noise, and hypersentitivity to all stimuli. When there's great exhaustion and mental dullness, combined with nervousness and oversensitivity, it's one to consider.
Potassium phosphate. Is used to supplement people deficient in phosphate; typically taken with water with meals and bedtime. A blood test for kidney function, calcium and other minerals should be done to determine if this is necessary.
