Eizen Tries De-Energy Drinks

In this episode of Eizen Tries... uh, Eizen tries out two flavors of Marley's Mellow Mood drinks (Berry and Citrus) and one of the Neuro Drinks (specifically Neuro Sleep). As you can probably imagine, these drinks help promote drowsiness to help you fall asleep better. Does it work, and if it does, why do they contain so much sugar?
