With DS1 - This certain air freshner. To this day I still can't handle it either, yet I was fine with it before pg. Cigarette smoke too.

DS2 - My own perfume, and mainly really sweet perfumes. I'd have to hide my gagging and stuff when I'd walk down the street. For a while there in the middle of the pg mostly I couldn't handle the smell of meat cooking and this certain pan I couldn't handle the smell of anything cooked in it.
