That's really good if you can use wipes or brush your teeth or whatever and your fine, even if it's for a short while.
My problem comes from my stomach, so I could brush my tongue/teeth, floss all I want to. The strong smell returns in minutes and quickly fills up the room.
I know very well what the OP is saying. And don't bother to go to a supervisor or HR. it just makes it worse. I did that and they joined in all of the mayhem right along with everybody else. Sometimes laughing at me right in my face. Many days I cried so much I soaked through all of the paper work on my desk.
The only thing that gets me through many of those kind of days is prayer. That God will ease the emotional pain your experiencing. And also to keep searching for a solution to this crippling disorder we have.
