I started taking this medication ten years ago i wish they would have given it to me sooner for years i suffered from heartburn they called me the relaid kid and in my later years mostly at night while sleeping my food would come back up then i would inhale into my lungs and i thought i was a gonner it was acid reflux thanks to this medication i have been heartburn free for ten years and i can eat just about anything.it does give me some mild stomach pain but its a lot better than having heartburns day and night
