It was quite a revelation to learn that my chronic nausea was a more severe form of reflux. A PPI helped tremendously for about 18 months. Then I discovered that long-term use leads to thinning bones, neuropathy, and dementia. SO I am now tapering off. I am getting a little GERD, which is tolerable, but not that horrible nausea. I also have inflammatory arthritis and so try to eat mainly anti inflammatory foods. I just wanted to share this to add to your information pool. Kindest regards.
