Hi, Kris.
I have a lot of your symptoms. Right now I am trying to balance a gastroporisis diet, lactose free diet, and gluten-free diet. What is good for one diet is not for another. It is a balancing act.
Have you been tested for gastroporisis? It is called a GES--gastric emptying scan. I do have IBS, but I also have gastroporisis, reflux and gerd, gluten intol., lactose intol., and possible SOD. It sounds like you need to find a different GI doctor and get proper testing. Irisart
