Someone at work always seems to use some sort of air freshener or something, and instantly after I walk into the area, no matter how much was used, I start coughing and hacking, I've asked them to stop, I've done this more than once, and they still do it. Today I threw up, I don't know if it's the cold plus the allergy symptoms I normally get with this, or just that things have gotten worse. I really really would like to not feel sick every time I work with this person. What do I do?
