Lotophagi

In Greek mythology, the Lotophagi ("lotus-eaters") were a race of people on an island dominated by lotus plants. The lotus flowers were the primary foodstuff of the island and it caused the people to sleep in peaceful apathy.

When Odysseus and his men landed on the island of the lotus-eaters, they began doing as the natives did, eating the lotus flowers. This caused them to sleep and stop caring about ever going home. Finally, Odysseus managed to rescue himself from the apathy and set sail.
