I was put on protonix for my gastric ulcer in 2011.
I followed the ulcer diet, but I did not listen to the gastro doctor and kept drinking coffee, diet cokes, and warm/cold beverages.
My doctor had to switched my meds to Nexium at the beginning of 2012 because I kept having pain. (I know it was my fault because I didn't follow the liquid portion of the diet.)
I am doing much better, but it's still very hard to accept that I won't be able to drink coffee, cocoa, diet cokes, tea and warm/cold beverages
Call your doctor if you weren't given a diet. The list is long: spices, ketchup, mustard, pickles. I ate a lot of chicken and tuna in water last year.
