We find that 1 part Apple Cider Vinegar (Braggs as Wombat sz) and four to five parts H2O knocks acid reflux back almost every time. Do it right away, at the fifrst hint that aciud reflux may occur. It can work. My sweetie at times unfortunately has had to take a several medications that cause reflux. And in typical doctor fashion, was prescribed expensive meds (Nexium) to counter expensive meds. No more.
