Sorry to read you are having a hard time. I too am an allergy sufferer.

Have you seen an allergist? Are you able to get allergy shots for this? Too bad you don't have another bathroom. 

I have been particularly vulnerable these days to vinyl and rubber. I have to be careful if I'm in a store that sells things like welcome mats. Even if go by an aisle without knowing it's there, I soon find out. My nose plugs, my eyes burn and tear, head pounds, dizziness and nausea. At that point I have to get out of the area as soon as possible or I'll vomit or faint or worse-both. Fresh air and water are the best things for me along with aspirin and an allergy pill. Sometimes something like chlorotrimetron helps. Sometimes I'm ill for a couple of days depending on how long the exposure. Sometimes it triggers a migraine.

I found out the fumes produced from those products aren't good for anyone.

I think the best thing is to see an allergist. Good luck, CyndiA. Feel better. Many blessings.
