Hello, Welcome to icliniq.com. I have gone through your query and understand your concern. What you are describing can happen after long courses of antibiotics, dental surgery, and changes in acid-suppressing medications. The improvement in your severe heartburn is reassuring, but the ongoing bad or vomit-like taste, mild throat burning on waking, and nighttime flare-ups suggest that you may still be having some reflux, especially silent reflux (laryngopharyngeal reflux), where acid or non-acid contents reach the throat and mouth. A few things could be contributing: Long-term antibiotics can change the normal bacteria and yeast balance in the mouth and gut, which may cause an unpleasant taste.
