I have that reaction to smokers who recently had a smoke and to many perfumes. I just try to avoid people as much as I can and drug myself with ibuprofen, antihistamines and an inhaler when needed. It sucks, but I have found when you tell someone, "I am allergic to your perfume, will you please refrain from wearing it around me?" they tend to hear, "You stink and I hate you and want you to hate me too." Of course with the smokers, if they aren't going to quit smoking for the betterment of their own lives, they certainly aren't going to quit smoking at work for me. It sucks though.

I have a job that has a policy against perfumes, but it isn't very effective. There are three of us in the office who react to perfumes and one complains to management about it semi regularly. They have responded by sending out a mass email asking not to wear it which stops people for about a week and then it starts again.

Heck, even my friends who know it makes me sick continue to wear it around me.

I guess I've just given up on my own comfort, not to say you should.
