I hope one of these things will help Brodie. I would definitely try the tablets Debbie suggested or the yogurt first.
What you said about the cleaner smell getting to you made me think of Richard. He can't handle anything Pine Sol smelling because he says he remembers in grade school the kid next to him throwing up everywhere and the janitor cleaning it up with pencil shavings and then mopping it all down with Pine Sol. He almost turns green when he smells it today. LOL.
I hope Brodie gets some relief soon, poor little guy.
