Hi Mrsfarmer
I in a way went though what your hb had gone though, but not to his point, I could not be around anything that had a chemical smell to it at all, even just having a beer I would have to put my head outside the window and trust me at -20 below it was the only relief I had but even the smallest of smells that were related to chemicals I was having problems as I was chemically sensitive to all smells, but I had an overdose of paint chemicals as a auto body painter and is called MCS as it really wrecked my life into the world of A/P and the effects of neurotoxicity on my body.
