Wow !! Hopefully you can get some relief. I have Barrett’s but try to keep it in check. I take a regiment of vitamins, before and while taking them I eat a banana which helps me swallow all them. Try eating a little banana before the pills and see? My daughter is on dialysis and just had a Thyroidectomy and also vomits continually and suffers from Gerd. She’s 36. Wishing you the best 🙏🙏
