How long after Communion do I wait to eat?

Being a new Catholic I now receive Communion. After I leave Mass, I wonder if I must wait a specific time length before I eat or drink anything, as we must do for an hour before Communion.

The Church doesn’t mandate a post-Communion fast. You’re free to eat or drink whenever you like after Communion. However, since the time the Real Presence is thought to remain after reception of Communion is about 15 minutes, you might choose to wait that long as a personal devotion.
