Heather, it happens to me too.  In stores, resturants and at home.
My daughter moved back home and put purfume on the other day and I spent my evening in the bathroom.   I told her to keep it in her car.

I finally gave up and bought a mask with filter that I wear anytime i go out. It helps but isnt completely foolproof. It is very frustrating to be so limited.

Soooo agree heather

Before I was sick I used to think Walmart and libraries were just a signal to my system to go to the bathroom; turns out it was likely the scents and mold as now I get anaphylaxis from it

I can do the grocery store if I speed walk past the detergent aisle

If I have to get myself soap I hold my breath and still get mild symptoms

I can't do restaurants yet because cooking smells are such an issue

I feel like a dog because when I walk past people I can smell the last meal they had, if they have a new car, fabric softener, detergent , cologne....a new way to see people and I don't like it!!
