For some folks, like myself, it was admitting to myself that I needed to change my diet and eating habits, and I haven’t had issues with acid reflux for years.
On the other hand, lots of folks have issues with this stuff no matter their eating habits and it is horrific to live with. As OP pointed out, things like GERD affect a lot of people.
That these people would take advantage of people in that situation is so infuriating.
