It probably depends what the reason was for the reflux in my case gallbladder.I had gallbladder inflammation, thickened wall and gallstone. My gallbladder is back to normal, I still have stones but no more symptoms.
Make sure that you keep flushing till for 3x you don't see anymore stones/sludge and then you can change to a couple of times a year for maintenance.
Bile is needed for digestion, so a clean liver/gallbladder is important.
