It's normal, coffee has caffeine And the explosive diarreaha (I know it's spelled wrong) is a common effect. It's good that you're getting cleaned out!
Caffeine is an irritant to the bowels. Hot liquid also makes you more likely to need to go. As my grandma used to say after drinking tea, "that's cut a path right through me".
Hey eva and adolf, are you two a couple in real life? Do you even know each other in real life? Maybe you should hook up. About the coffee, its a diuretic, silly
I don't know about that.. It may just have to do with how sensitive your system is. You could always check with a doctor to make sure there is nothing wrong.
