erosive esophagitis
"I've had acid reflux for 4 years. My doctor recommended Prilosec, etc. None of the over the counter medicines worked. Some mornings, I would wake up with a mouthful of acid. My voice was becoming more horse. On some days I could barely speak and thought I would lose my voice entirely. 
My latest Doc prescribed Dexilant after giving me some free samples.
Within a few days, my throat was better. I've been taking it for 1 month and my voice is almost back to normal. So far, I've had no side effects, but will taper off the medicine so I don't get weakened bones due to lower calcium intake. The doc gave me a discount card, and insurance covers all but $20.00."
