I also want to add in something else. Even though I don't know what the results of my blood tests will show or whether I will have to get one of those upper GI series, which I will do if they want me to do....
When I get stressed or nervious I tend to tighten my stomach really really hard. It is almost a knot. During periods of high stress that knot can stay there for days. I am starting to think that this tightening is bringing up stomach acid, lots of it into my mouth.
Well, I'll know soon. I'll make sure to tell my doc about my stress problem to see if this is something that will cause the BO.
