I have periods where I am perfectly fine and flare ups now and again. I find licorice tea soothing In fact; there is a licorice liquid that I buy (has the consistency of molasses that works wonders for soothing the lining of the g.i. tract. You take about 1/4 tsp+ and make a tea. Anyway, for the most part it's more or less under control. Gaviscon is not harmful. A little magnesium carbonate won't cause any trouble. Oh drinking water is good: pushes the acid down the esophagus.
Anyway, I'm good with the status quo.
