Every morning, I tumble out of bed and stumble to the kitchen and whack a heaped tablespoon of coffee in the cafetiere to make myself a Big Breakfast-sized mug of black, unsweetened coffee. I make another cup as soon as I get to work, and usually go through a can of Coke or two in the course of a working day. Are there any bloggers who don't survive on excessive amounts of caffeine?
