INTRODUCTION. Gastroesophageal reflux, also called acid reflux, occurs when the stomach contents back up (reflux) into the esophagus or mouth.

How often to replace: 1  Mascara: every 3-6 months (which means youâll have to throw it away before itâs used upâ¦ the same goes for a lot of these products, probably) 2  Eye shadow: every 6 months. 3  Eyeliner (liquid): every 3-4 months. 4  Eyeliner (pencil): every 6-12 months.
