Very few of us would be brave enough to claim to be cured even if we hit a long lasting good phase. If you'd asked me in 2007, I'd have said "Yes! I cured mine with DGL!". It came back 3 years later though and responds to very little - the drugs keep a lid on it, just.
Some people manage to get their GERD under very good control so that if they stick to a particular protocol things are good - like the Koufman diet, other low fat diets, going vegan etc.
To me, cured means being able to take in so much red wine that I need a big mug of coffee to sober up - and having no heartburn or reflux afterwards!! I would, however, settle for one glass of red wine . . .
