Nobody probably cares BUT, I've suffered from SEVERE acid reflux disease & GERD (most people think they're the same thing but they have a few differences) since about sixth grade.  I've been on Nexium for the past 9 years but lately I've been still getting heartburn almost every other day and i'm going to say LISTEN TO YOUR GRANDMAS REMEDIES.  I recently learned mixing a tablespoon of baking soda in about a little rinse cup and drinking it neutralizes it instantly! Give it a few seconds, you'll probably let a few big burps and VIOLA! heartburn gone.  It's seriously been a lifesaver.
