Wow Moot!, I was going to suggest herbalife green tea concentrate w/ it's antioxidant and thermogenic benefits of green tea and fast-acting botanicals for energy and weight-management support low in calories and carbohydrates, but your suggestion was a tough act to follow, lol.
I put a couple small scoops of green tea concentrate in my cold aquafina bottle, shake it up real well, and pop a couple small b-12's down the tube and I'm wide eyed for hours on end. Oh, and it will also help u in the "not roll out of bed" department also. Just the facts mam, just the facts.
