Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you are suffering from Gastroesophageal reflux disease commonly known as Acid reflux and it occurs due to weakening of the band of muscles present at the lower end of the oesophagus/food pipe leading to reflux acid and food particles from stomach to food pipe and throat.. I would suggest you to consult a Gastroenterologist and get evaluated and a thorough clinical evaluation and investigations like upper G.I Endoscopy can help in diagnosis and treatment can be done accordingly.. Medications and dietary and lifestyle modifications is the only way to control it.. You can be advised to take Proton Pump Inhibitors like Omeprazole or Pantoprazole that you are already taking.. Take antacids like Milk of magnesia before meals.. Avoid spicy food and drink plenty of water.. Always take walk after meals and take your dinner atleast 2 hours before sleep.. Take small portions of food every 2 hours.. Avoid heavy or large meals.. Take walks after meals.. You should sleep with head and chest slightly raised as compared to feet.. If nothing works surgical correction can be checked for.. Hope this information helps..
