I'm so sorry I only saw this today. I got slammed with work and wasnt monitoring mayoclinic closely. I don't have sore throat or acid taste. I have a chronic cough and voice hoarseness. I had reflux/heartburn evey evening, especially if I lay flat, like for exercises and at bedtime. Now that I know about LPR, I am much more aware of these things. Esophageal guardian at bedtime, which i follow with about 4 ounces of natueal alkaline water, gives me immediate relief. Better than prilosec which I never liked.
And I do notice more "heartburn " and voice changes after a meal with meat or dairy.
Good luck! I sincerely hope you find something that works for you.
