My dh has one of those machines. My coffee drinkage is usually restricted to dessert while dining out, as I prefer Coke as my caffeine delivery system.

Anyway, dh started making me these lovely iced mocha drinks. Lovely, until I started getting these mysterious headaches. Come to find out, each contained TWO SHOTS of espresso!!! So now I have a bag of decaf coffee beans. When I make one, I use all decaf, and if we're sharing, we'll split. Since I'm an infrequent drinker, I can't taste the difference.
