@stjohnsriverrat Thank you for this information. It makes me even happier that I dumped PPIs after being on them for four years. They damaged my kidneys and did leave me with B12 deficiency. If I had to do it all over again, I would have used famotidine, which reduces stomach acid much less than a PPI. I also would have changed my diet and lifestyle earlier. Many people can control their GERD on a low-acid, whole food diet (yes pills are easier but eating better has good side effects, not bad ones).
