There are times when my GERD is so bad that my Zantac just doesn'y work at all. It gets so bad that I spend hours in pain; pain that goes from the pit of my stomach, around through my back, up my spine and into my shoulders and even my jaw at times. I literally get sick and end up vomiting and breaking out on a cold sweat repeatedly for several hours.
Generally, when I vomit, I feel a little better, for a little while. While my stomach is hurting a little less, I take my Zantan and two TUMS along with an Aleve. I also take a drink of milk, but only a drink...enough to feel like it is cooling off my stomach lining, and I eat a piece of bread or a few unsalted crackers.
After 30-45 minutes the pain seems to ease up enough that I can get some rest. When I wake up, I am sure to take two more TUMS and my Zantac (as long as it is time for me to do so).
