Yep. I had favorite antiacids by the time I graduated from college, so definitely not just a sign of growing older. I don’t think I’ve ever actually gotten heartburn since it’s described as a feeling under your breastbone and I feel the burn only at the back of my throat. Zantac 150mg does a pretty good job keeping the throat burning away…but less so in the winter, though I’ve never been able to figure out why given my diet doesn’t change much then.
