Do you take any medications for nausea? I have been on Nortriptyline for years for mine, but I recently went through a very bad bout. My doctor upped my dosage and it really helped when it seemed like nothing else did. I hope you are able to feel better soon.

Domperidone sounds a little scary to me, it's banned in the U.S. due to cardiac risks. I would see if they would prescribe something else that you could take regularly. Ondansetron is another one that has been beneficial to me. I hate to say it, but I think meds are the only thing that can pull us out of a bad phase. I do know of some people that have had success with a low FODMAP diet, though.
