I noticed that after you take a shit, the smell lowers. You still smell, but very little. And when your close to going to the restroom, or have a smelly feces... you will smell horrible to other people. Trying going to the restroom before going to school, during lunch break, and after school. I stop eating before 8 pm. It sucks because you have to force the fecus. I believe it's something in the digestive system that is provoking this.
