I have severe acid reflux called Barretts Esophaegus (the precancer stage)
Earlier someone posted about questioning if diet soda causes reflux.
The caffeine in soda can cause acid reflux. Also, chocolate, citrus fruits, mints, tomatoes, anything with caffeine.
I am on several meds for my reflux, protonix, reglan, gas x, and levison.
I was on nexium for several years but it was giving me severe diarrhea as a side effect so my gastro took me off of it. He said for some people after being on it awhile they can develop side effects.
