Well I looooooooooooove tea, so that'd be my first choice
Lik PP's have said, have you tried it with honey/milk? I *love* Earl Grey tea with sugar/honey and milk. NOT skim milk, it basically tastes like watered down tea then! Or chai sweetened with milk, too.
A latte is espresso and steamed milk with a dollop of foam. A cappuccino is espresso and foam with a splash of milk (altho you can get a "wet" cappuccino which is more milk). There's nothing sweet about either of those unless you sweeten them. If you're talking about lattes and cappuccinos out of the machines at the gas station, just resign yourself to drinking hundreds of calories and fat.
If you were my customer ordering at Starbucks, I would probably encourage you in the way of a flavored latte (vanilla, caramel, hazelnut), caramel macchiato, or get the peppermint hot chocolate with maybe just 1 or 2 pumps of mint. Our hot chocolate isn't too bad calorie wise (except the signature hot chocolate which is like diabetic coma in a cup
) A tall nonfat, no whip hot chocolate has 190 calories in it, I think 2 pumps of peppermint would add 70 calories. A tall nonfat, no whip vanilla (pr caramel, or toffeenut, etc) cream is 150 calories. I believe the pumpkin has more calories (like the white mocha) but it shouldn't be like 10000 more or anything
Another drink that is deeeeeeeeelicious and completely rediculously high in calories is the caramel apple spice. But it's yummy!
