these are the classical symptoms of acidity, what all you have mentioned.
i would advise to avoid oily foods specially at night, if you cannot avoid, take these precautions- 1. have half glass of cold
milk before going to bed, this will reduce acidity. 2. don't sleep for at least 2 hours after dinner. 3. take two pillows beneath your head, to prevent water-brash. 4. you can continue the medicines what you are taking on as and when required basis.
hope this helps.
