We've all experienced cottonmouth before, and to say it's no fun is an understatement. Keep a convenient carafe set, complete with a drinking glass, by your bedside to ensure you'll never feel an excruciating need for water (without immediate access) again. You can refill the cup from the carafe to be sure your glass is always half full.
Pre-owned thermal carafe. Still has the sticker on the bottom. Button on top closes spout to keep beverage warm/cold. Tiny tip of glass on the pointy bottom of internal glass carafe may have broken off as it feels rough on the tip. | eBay!
