We will never know why but a few years ago. I had lots of these problems.

I went to gastro doctor and then another one. Because nothing was working.
It turned out that going on nexium after a couple of the other meds was
what helped me. Even to the extent I don't need it anymore. WHen my
stomach acts up I really watch what I eat. It seems to be good for
me. I do eat many blands anyway because it helps me.

And its what I like.
