Having IBS for 20 years & recently Acid Reflux(8 Months) This appears to be a bad combination.Its seems that all Acid Reflux Drugs,Pepcid, zantac, prilosec..make my IBS symtoms much much worse. Does anyone out their have this double trouble condition??and Has any natural remedy's worked?? Theonly thing thats helped me a little bit has been a product called dioxchlor..which has helped with both IBS & Acid Reflux symstoms.
