I'm surprised you got off omeprazole without doing it gradually.
If you feel some of the LPR symptoms, then you need to treat but I can suggest trying something other than omeprazole:
famotidine (an H2 blocker instead of a PPI),
or Gaviscon Advance (the one with alginate - it creates a barrier that blocks the acid from moving from your stomach to your esophagus. you can take before bedtime, or if needed also after meals), or Tums or pepto bismol.
Also, don't eat too big meals (don't drink after your meal), move around after you eat or when you feel fullness (so the food pulls your stomach down out of your esophagus), I find that taking probiotics helps, and small amounts of pomegranate juice. And don't eat 3 hours before bedtime. You can sleep on a wedge and/or raise the head of your bed. If you continue to have Barretts esophagus and can't manage with other ideas, then you might need to go back on omeprazole so as to avoid esophageal cancer. Good luck
