Andreas moritz have said himself the reflux is a enzym, low acid issue in the stomac. Correct me if im wrong.
And when I did my first flush I had similar to you. It went over after a few weeks. My teory is that some part of ur liver have been congested and also a bit enlarged, pushing toward your cardia and causing your issues. I think you should try do a flush with Epsom salt. I do not recommend using the medications.
