Are talking about reflux that is entering your airways? If so, there is a fix...you can get a Nissen fundoplication to tighten the LES. That will effectively keep the stomach contents from refluxing at high volumes and entering your lungs.
Have you discussed this possibility with your doctor?
Sorry to hear you're struggling!
