Have you had a test for Helicobacter Pylori? It is a bacteria that causes ulcers. I had it and only had acid reflux and heartburn. I understand some people don't even have symptoms, yet carry the bug. It is also contageous, usually within the family drinking after eachother, etc....
Anyway, if you do have it you might be cured and not have to use zantac anymore. That could cure one of your problems anyway.
