you realy need a gastroenterologist to see if you have acid reflux disease.
To treat this, the best is to fallow a blanf diet, with small frequent meals. The Acid reducer meds I am talking about some times takes up to 6 weeks to really have effect. The best one is Protonix, but this one needs prescription. Prilosec, is similar and over the counter med.
But you realy should not experiment, best to see a doctor, to get a diagnosis.
