Stand aside Starbucks Mocha Frappachino ®, there's a better wake-up call: grapefruit juice. A hefty dose of citric acid first thing in the morning is bound to wake me up. I found a freeware alarm program called Citrus, and a set of sounds to go with it called Lemon Juice. The author of Citrus also wrote a web photo album generator I might have to try. What's your caffeine replacement?
