I know its appalling, but this is my caffeine delivery system every morning within 5 minutes of waking:
32 oz plastic tumbler
Cold tap water
2 tablespoons anybrand caffinated coffee, stirred briskly.
I do enjoy the expresso on the streets in Miami, and I do enjoy a good cup o' joe when someone makes it for me, but in-between marriages I deteriorated into this "lowest work load per caffeine hit" method. (Wife drinks tea with milk.)
