In my experience, going off the PPI also required dietary changes. I went cold turkey since the GI who did my endoscopy told me to stop and never take again due to my cells being hypertrophic (very enlarged).
I immediately went gluten free, dairy free, sugar free (use organic stevia now), alcohol free, and switched to a low acid coffee. After 2 weeks I started feeling immensely better. Short version of my journey: After some testing, I learned I was gluten intolerant, had SIBO, a yeast infection and reacting to mold. I consulted with a nutritionist at my doctor’s office and she guided with foods to omit while my gut healed. And foods to definitely add to my diet.
Getting off a PPI can be done with the right help.
Best to you, I know it’s not easy.
