If I can make a suggestion... individual packets of gatorade, or some other electrolyte replacement crystals would be a better (& cheaper) option. Maybe attach a couple of Tylenol to it & a little note saying "Too much fun in the sun & tequila in the belly, drink me before bed & you'll wake up feeling jolly!" or some other corny quote. IMHO, keeping it (hangover) from happening is better then trying to get rid of it. LOL
