It might be helpful to discuss the issue with a local practitioner. I would specifically mention neem, an Indian herb which has been used by my patients successfully to wean off Protonix. By using the leaf or bark (not the seed, which is more toxic) they find a reduction in acid as well as a repair of the gastric lining which does not occur by using the drugs. This is documented on medline if you search for GERD and neem.
I hope this is helpful. Please do not use it without consulting your local practitioner.
