A couple of weeks ago I started taking 1 tsp of turmeric (just the powdered spice) in a small glass of water twice a day (for liver function), and without taking the water cure, my acid reflux seems to have subsided. I now just take the turmeric once a day, because taking it late in the evening seemed to be keeping me up at night.
Yesterday I didn't take the turmeric, and by evening I had severe reflux. Too late to take turmeric so I took 1/2 teaspoon of unrefined sea salt and a large glass of water, and that gave me relief almost instantly.
Although the spice is a little bitter, there is no aftertaste or repeating (burping). So it may sound unpleasant, but it's really not bad. I take a small spoonful of honey afterward, or a sip of tea.
I have read that turmeric is more effective when taken with black pepper, so I try to shake a bit into my drink. I also just read that it's much more effective when warmed up in something containing fat--like food! or even milk or coconut milk. Apparently in India it is taken as a tea with milk.
