zegerid is an immediate release proton pump inhibitor, ppi.
Not sure if it will cause dry mouth, but meds effect everone
differently. I was taking protonix for a long time and
didnt get much relief, and didnt like the side effects, I found
an organic drink called Haldi, at Whole foods markets
in New York and DC area, and it helped me come off
my ppi. That may be an option for you, but do not
just take yourself off of meds as a general rule. Good
