Hi Robert
Some people can take PPIs and seem okay. But for some, PPIs can make the problem worse. This is due to PPIs changing the amount of acid & enzymes in the stomach required to break down food. When the amount of acid in the stomach is incorrect, then the LES (valve) will not close. Both food and the remaining acid is pushed back up the esophagus making things worse. This can cause worse GERD, regurgitation, and vomiting like symptoms.
The mucus in the throat is a typical symptom of LPR (silent reflux). With silent reflux the acid goes all the way up to the throat area. The body produces mucus to help protect the throat from the acid. The mucus can cause a lot of coughing to trying to clear the throat area. The burping and bloating is usually from food not being properly broke down. You can wake up the next morning and still be burping before you even eat or drink anything.
I should also mention some people experience a withdrawal symptom from PPIs called Acid rebound (hyper-secretion of acid), which can make it difficult to wean off a PPI.
You might want to google, LPR, silent reflux, acid rebound, and low stomach acid
