Just found this thread. I have suspected LPR, according to ent, and short barretts, visually on endoscopy but negative for barretts on pathology after 5 months on omeprazole.
My ent recommended a plant based diet but with animal protein in small portions 2 to 3 times a week. He also recommended reflux gourmet, which has sodium alginate, to create a reflux raft above stomach contents and keep acid in stomach. I found esophageal guardian by life extension which costs less and works better for me. I take it at bedtime.
Waiting to hear from GI that I can wean off omeprazole, which I already stated doing every other day. So far so good.
