I love the frapuchino's they sell in the fridge's at 7-11's & mini-marts. Also the starbucks doubleshot is pretty good. I pretty much take an iced coffe over a regular one, but its all good. That said I only really drink that stuff cause I like the taste, I never need it to stay awake or wakeup. I do pretty good on little sleep. I've been going to bed at 2 and wakin up at 6:30 al year with no problems.
