Hi I Have Been Having Problems With My Digestive System.

Hi I have been having problems with my digestive system. I don't know if I'm producing too much acid or not enough. I do have acid reflux or at least that's what I think it is. My family Dr put me on a medication called Tecta but they don't work anymore. After eating a meal an hour later I feel so hungry again. It feels like I haven't eaten anything. There are a lot of times just after I have finished eating my food will come right back up my throat. I could go weeks without a crimps stomach and then I could have a crampy stomach all day. Don't know if this is related or not.
