I have it too. I have been taking ACV with Baking Soda for about a year. Just had another biopsy - Dr. Said all is well. I will take it the rest of my life to prevent this from spreading.
Apple Cider Vinegar
If you use apple cider vinegar, be sure to use the kind with the "mother" in it - the cloudy stuff that drifts to the bottom. If I have a symptom I find it works - and I add a tsp. of honey. Also, use a good digestive enzyme with first bite of food and a probiotic each day. Don't eat fatty foods and avoid wheat and dairy. Get adequate sleep and exercise a bit. These measures can be difficult but it's absolutely worth it. I don't have to take the worthless and dangerous meds and haven't had heartburn for months. (My doc says it's okay unless my bi-annual scope tests shows further damage -- which they haven't. )
