barrett's esophagus
"Took this drug for 5 months for acid reflux at nighttime unknowingly acid splashed up in my throat giving me a continuous sore throat during the day. The side effects it caused was a major concern; i.e., reduces stomach acid up to 80% resulting in poor digestion and absorption especially B12 and Calcium.   I found that my stool was long and very fat, (uncommon for me and indicative of poor digestion/absorption). Another side effect was a very bad dry mouth AND, extremely dry hands --constantly wrinkled up --like when one sits in the bath tub for a couple hours. I stopped taking it and now take a couple of Tums before bedtime."
