Unless the OP is affected with some kind of synesthesia where odours trigger discomfort/nausea/migraines.

I admit that I don’t really understand what LP needs to avoid, but he may not know either.

Occasionally, walking through perfume halls in department stores, I get sneezing fits and/or painful, watering eyes. And yet I may well walk the same route through the same department on another day and am entirely unaffected. Goodness know what the trigger is.
