And scents? Alcohol, tobacco, and perfume are high on the list. Even a trace of anything like that can feel like a spike up the nose. An open glass of wine at the far end of the table is enough. You can put on a dab of perfume in the morning, shower in the afternoon, walk across the room in the evening, and it'll still be painful to cross your footsteps several minutes later. (I'm not kidding. This has happened.)

I relate to this comment SO, SO HARD.

I have found something which helps some - not 100% - let me know if you're interested in hearing about it, I don't wanna be all unsolicited-advicey at you. ^_^
