Ah spicy food, the only food you get to taste 4 times, when you eat it, when it hits your stomach, when it reaches your colon, and when it leaves out of you as poop, the ones in the middle are the worst ones
The snot and tears while you eat can be managed with some milk, it is also the perfect excuse for ice-cream, but nothing will save your intestines the next day
You may think that water and soap will save you? but that only covers your butt hole
Your insides will still burn, and you are not supposed to give yourself a soap enema, you have to deal with it, luckily the inner burning will go away within the next hour after pooping, it may feel like ulcers, but don't worry they are not, check your poop for blood before flushing just in case tho, if there is blood, it was from a preexisting condition and not because of the spice, the spice just so happened made contact with your wounds
Spicy food gives the fastest poops with the longest consequences, which is why i only go for medium heat now, maybe a bit above if i am feeling unwise
