There's something in your spice mixture that not only stings the tongue, but also the stomach, then the intestines. I felt horrible the whole day after lunch, with this burning feeling in my tummy gnawing at me. It was as though the chewed and digested Mega Mcspicy burned whatever part of my body it was in contact with.

This cumulated into several bad episodes of very painful diarrhoea at midnight. Being medically trained, I knew that it wasn't harmful yet so I did not see a doctor.

A quick search on Google shows that I'm not the only one.

calamariforthought had a serious stomachache:

1 more minute. Feeling of involuntary rectal movements. Something is coming down. I know I cannot endure another 3 more bus stops. I will crap in my pants and everyone on the bus will know.

I pressed the bell. I stood up. Squeezed my way to the exit. Bus is waiting at a junction to turn right. Long queue of vehicles. Light just turned red. I stood at the exit, legs crossed. Closed my eyes, focusing all my strength to squeeze my rectum shut, holding everything in.
