                                            It can be GERD or reflux.
Detailed Answer:
Hello dear, welcome to Ask a doctor's service.
I read your query and here is my advice.
I think you are having reflux or GERD which means returning of the stomach content in the throat and mouth which is causing the citrus taste. Also the burping maybe caused by GERD.
Lipitor may have this side effect while other medications you are taking don't cause this side effects.
You can try some tips to reduce the acidity and reflux.
Don't use much fruit juices, sweets, fruits like oranges , sauces, tomatoes etc.
Reduce alcohol, caffeine, chocolate,
You can eat at least 3 hours before bed.
Sleep with elevated head with pillows.
You can use over the counter antiacids also.
Hope I have answered the question.
Let me know if I can assist you further.
