I don't know what I can tell you for not having had the problem as you have had. I'm sorry you have this problem. :-(
My MIL (motherinlaw) has asthma really bad at times. When it it acting up for her, her breath will stink up. At least she and other people know the source for her problem.
I have been part of the curezone.com for about a year now, but recently began posting again. I'm more of a reader than a poster here.
