J: I'm so tired! I don't know how I'm going to make it through this lecture.

S: The professor is a bit boring today. You need something to (perk yourself up). How about a coffee?

J: I don't really like coffee, to be honest. It's too (bitter) for me.

S: Well, you need something to wake you up. How about a (soda)?

J: Most soft drinks have too much sugar in them.

S: The (diet) sodas don't have any sugar in them. Which one would you like?

J: I like diet Sprite. Does that have any (caffeine) in it?

S: Unfortunately, it doesn't. How about some diet coke?

J: I don't care for coke. I heard that coke was first used as a (medicine) and I don't like medicine. What else has caffeine?

S: Maybe you should try a cappuccino or a latte; they taste much better than (plain) brewed coffee.

J: Maybe. How about a mochaccino? Are they any good?

S: You'll love that. It's just a shot of espresso (beans) mixed with steam milk and some chocolate syrup.

J: That's perfect! Would you like one, too? My (treat).

S: Thanks, but I'll stick with some jasmine tea. I'm trying to watch my diet.
