Has the cure for your hangover been in the pantry this whole time?Pedialyte, the drink designed to replace fluids that are lost when a child is ill, is starting a new campaign to let adults know that if they've imbibed too much, their product can help. Since 2012, use of the drink among adults has increased by 57 percent, and the "See the Lyte" campaign is appealing to that demographic, using catchphrases like "When last night's party threatens to ruin today, those in the know reach for Pedialyte."This month, the company is launching a new powder in orange and strawberry lemonade flavors, making it convenient for adults who don't want to lug around the jug the drink comes in now, and they plan on passing out samples at concerts and sporting events. While it's not a cure, it does help adults when they are dehydrated. "The thing about Pedialyte, Gatorade, and things like that, there is an optimal concentration to absorb glucose and electrolytes and fluid from the intestines," Dr. Robert Swift of Brown University's Alpert Medical School told NBC News.
