Did you go on a low choline diet for tmau? Try asking again for h.pylori test from another doctor. Maybe you could try food allergy tests from a naturopathic doctor or some of those tests as seen on doctorsdata.com. It's so depressing I know. Today on the bus a girl was saying how she couldn't breathe and she went on for about 5 minutes. Before someone said they would not allow themselves to smell like that about the way I smell. Like I "allow" myself to smell like this, I have no choice as you can se eI tried everything. There really is a lack of empathy on this problem that it could happen to them because it is so rare and they think we are dirty allow ourselves to smell like that and there's a simple cure. There are strange afflictions out every day. I don't know a lot about breath odor but maybe you can try the one prescribed by the dentist. I've been praying and looking for years and still I have no cure. Maybe there's some lesson Im supposed to learn from this or this is one of my burden in life.
