Question

What effect did spending time with the lotus waters have on Odysseus men?

Answer 1

The effect of the Lotus Eaters wasted the time of Odysseus and his men.

For a better explanation:
When Odysseus' men went onto the Lotus Eaters island, they were encouraged by the natives to eat the Lotus plant. This plant acted as a type of drug, causing the sailors to forget about their home and their goals. Instead, the sailors only wanted to stay on the island, eating more Lotus plants.
