Can I Persuade My Husband to Stop Drinking Diet Doctor Pepper?

A librarian asks Hank and John if they can persuade her husband to stop drinking diet doctor pepper. Hank: Your husband should be drinking a diet doctor pepper a night, at least at least one. But here's the thing, cambucha is good for you. It has a lot of probiotics. And i'm not telling you to stop drinking cambucha, but i am telling you that it has more sugar in it than diet doctor pepper - which is a delicious, zero calory drink.
