Working a technical job can really drain your energy and vitality.  Big Time. This drink supplies me with the energy I need to exercise after a mentally exhausting day at a desk at work or a week full of travel, hotels, long meetings and restaurant food.  It provides electrolytes and yet has this really gorgeous taste, unlike some other electrolyte replacement beverages. 

You do need to watch how many you consume in a week however, due to the amount of calories it contains.  There are two servings in each bottle for a total of 200 calories so you don't want to drink this without exercising...
