Vampires dont have to drink blood but it becomes unbearable after a unknown length of time. In the books it feels like their throats are on fire or extremely painful. If they don't feed for a while they become uncontrollable and highly dangerous killing anyfhing that gets in the way of his/her feeding. Only those with a extremely high amount of self control like Bella Swan or Carlisle Cullen could resist.

Note: The last part is only a theory but its highly possible.
