Why does vomit, feces and urine smell so bad? I have been having vomiting attacks almost nonstop for the last 6 months. I cannot go to work because I am afraid that I will vomit inside the building I working in causing a foul-smelling mess and someone will have to clean after me and I don't want someone having to clean that after me. I cannot drive a car because then I am afraid that I will have to vomit while driving the car, losing control of the car and crashing possibly resulting in my death. I also do not want to vomit on my clothes while in the car because my vomit has a very bad smell. So I wonder, what can I do in order that these things will not smell so awful as they are now?
