Replying to So i got a new puppy

I got a new puppy, shes's about 9 weeks old now and her name is Sugar. She is a Schnauzer(sp?). Anyways she won't stop fucking biting. And its starting to hurt. She has her quiet and calm times but then she starts gnawing on my feet and shorts, everything. I know puppies usually naturally do this but how can I stop this. She probably thinks she's just playing but people don't like it, obviously. Everytime she bites, we say "no bite." Soemtimes she stops. She knows what it means but is very stubborn. What other ways can I decrease the biting. And no, im not gonna smack her in the face. Any help would be appreciated.
