Hi Alfred89,
Thank you so much for your advice.
I used to do all of this at work in the bathroom and even if I just brushed my teeth or used listerine, people would cover their faces. I think what has helped most of all is diet change but it has only prevented people from covering their faces, not from making faces and making nasty comments. Unfortunately, my breath comes out like a gas which along with my BO fills an entire half of the mall I work in (because I am there so much). Dentists and doctors have confirmed that the smell is not coming from my mouth because I am ridiculously hygenic. I believe mine is coming from my stomach because I can smell the gas a little when I am sitting on the floor and hunch over. Its like sitting this way pushes the gas further out from my stomach. Also customers react more in the store when I bend down.
