Seriously? Coffee actually has a lot of fiber, which is why people often end up running to the bathroom after drinking it.

you don't drink the fiber son
the reason you run to take a shit after a coffee is because it's a stimulant type laxative

it's the same reason why ( hopefully ) you don't shit while you're sleeping in bed at night
when you sleep your intestine goes into sleep mode ... when you drink coffee it goes into sprint
Oh I only drink energy drink poison
