I read an article about "functional medicine". There is such a thing. This person had to have a tube inserted in her stomach. She was that bad. And she had pictures of herself so thin and tired. Now. She claims she is has no issues. She went to a Functional Medicine Clinic. She ended up helping her diet (which I assume you have been avoiding the foods you are not to eat) with adzuki red bean paste which add protein and beet kvass. She also said that sometimes you can be misdiagnosed and have hypochloridia. Don't know if functional medicine is a choice but it might be worth a shot. Does Mayo Clinic have a functional medicine department? I have this disease and did not take the medicines. My gastroparesis said to try iberogast. It is natural drops that go into a trip before or during your meals. It helps the motility of your stomach and it works for me. When I have the coughing fits, I resort to sugarless gum. Works great! I also have a 5-7" wedge until my mattress to elevate my heads and I sleep in my left side as the right side is a straight shot to your stomach & you can get reflux. I do exercise twice a week too. And avoid ALL of the foods that they listed.
