I started having acid reflux/occasionally heartburn maybe 1.5 -2 years ago? I've taken Prilosec daily since....it doesn't bother me anymore.
Regarding the "pain" I describe - I did some research on gallbladder stuff, and while the location seems right on, the symptoms don't. I guess "pain" is not really the right word to describe this. It is just dull pressure. It never outright "hurts" - never seems to increase in intensity when it is present.
