yeah, I didn't think a diet change would do it for me either. I was eating a whole large bottle of Rolaids or Tums
EVERY DAY along with my prescription medication for it.
Suddenly, one day during my dieting down phase of the reconstruction of me - I realized that I hadn't had a tums in over a month. I dropped the prescription to see what would happen. No pain from reflux since then...ever.
I still get the growly, rumbly, rolly stuff in the lower abdomen from
high carbs but no more reflux.
It's worth a shot to experiment with your diet and see if it can at least help some.
