Kevin Warwick on caffeine.

Caffeine How I learned to stop worrying and drink coffee already. Kevin Warwick in Chicago decides to become addicted to caffeine via coffee doses. Tries various brands. Ultimately ends up liking it too much. It's a steady slide:

"Here's the thing about Starbucks: it's not bad at all, it's just juiced with caffeine. Not Barry Bonds juiced, more Rafael Palmeiro juiced—because he didn't seem like he had it in him. Making such a significant jump in caffeine seems ill-advised, but I went ahead and ordered a 12-ounce—ahem, "tall"—anyway, nearly doubling the amount of caffeine from yesterday's ten-ounce serving of Dunkin'. I've been in a Starbucks before because I am a human, but once I was ordering something other than decaf tea or coffee cake, navigating the menu of mochas, macchiatos, lattes, and cappuccinos felt on par with placing a bet at a Vegas sports book."
