How can you be so sure that it's flatulence? I think that you are mistaken in thinking that this is mere flatulence. Flatulence doesn't get stuck for 2 days. What you are trying to push out is a bowel movement but you can't because you are constipated. Eat more fibre and drink more water. If that doesn't work take a herbal laxative.
I can't say that I'm surprised. Taco Bell is apparently mostly made of oils. There was a huge controversy a few years ago because their "meat" consisted mainly of cheap oils and other filler.
Confession time: Those Petite Chili Pepper colour varieties seem to make me go. I've eaten them with rice and they almost always give me something close to diarrhea. If I rice by itself the end result is usually constipation. If I put those same peppers in a dish with tomatoes or some sort of vegetable, I can't go!
it does the same to me i ate a full jar of jalapeno peppers and had the poops really bad it was pure watery poo i've not done that again it made my butt sore.
