My new 'fave'. These give you the vitamin boost you need and the energy / clarity you want. Without the bad (coffee) breath afterward, artificial colors, sweeteners or crash. You get 20 'tabs' per box so they are about 1.40 per drink (verses +/= 2.50 ea like coffee, other popular energy drinks). Come in pomegranate or lemon. Just drop it into a cup of water until it dissolves then add ice. No need to lug cases of drinks around -it fits in your pocket.
