Janet, I understand your problem but all the talking leads to nowhere. What is yuk about a gastroscopy? It's a great way to get your stomach checked (biopsies included). You can start praying that you never have to do a coloscopy because you will need a stronger word for it than "yuk". When I take betaine HCL things get 1000% worse for me. As you said, you don't have issues with energy, there is no excuse for you not to go to a gastroenterologist and get the basic science done. If they find nothing, great, then you can start looking at other possibilities and will never have to worry about more serious causes of bloating. ME/CFS people would do any test in order to get treatment or to know the cause of their disease so it's kind of funny that a healthy person doesn't even want to do basic/standard tests because it includes going to a doctor twice.
