Ranitidine
"19 years old, suffering from extreme acid reflux for the past year... after getting to the point where 4-6 Rolaids wouldn't cut it after a meal, I started on Protonix-- bad idea, make me so sick I couldn't stand it. Tried ranitidine next... so much better! I hardly ever feel sick, and when I do, it's only from super-spicy food. I love ranitidine!"
