barrett's esophagus
"I suffered from GERD for over 4 years and have tried everything.  I was eating Tums like candy and taking Prilosec.  Then I started with the acid reflux in my sleep and woke up gagging and vomiting.  I had a scope 2 months ago and was told I have high-grade dysplasia Barrett's.  Doctor put me on 60 mg Dexilant daily.  Within 2 days I was in heaven!  Works wonders but now I have diarrhea that is constant.  It started a few days after I started to take it.  Other than that, it works wonders.  I can actually sleep in my bed instead of the recliner."
