Omeprazole
"Doctor put me on this (20mg) because I told him I had really bad heartburn that wouldn't go away. Started taking it and felt immediate relief from the acid coming back up in my esophagus. I didnt really have any feelings of heartburn while on it. The only problems I experienced were a little indigestion in the beginning, like there wasn't enough acid in my stomach to digest to food properly. So make sure you chew your food really good and sip water with your food here and there. My bowels were okay, it just looked like my food wasnt 100% digested and that maybe I didnt abosrb all of the nutrients from the food. But it is well worth it because after a month of taking it, I stopped completely, and have only had heartburn a few times since then"
