Hi I was constipated and drank magnesium citrate two nights ago. By today my stool is black, runny, and oily/greasy looking. What should I do.

In brief: Truly black???

Black stool indicates possible bleeding ulcer or blood loss somewhere in the proximal GI tract.
You need to see your doctor as soon as possible to check it out.
