What have latter-day prophets said about sleep?

[moonman239]

I was listening to a Mormon newswoman talk about sleep. She said that latter-day prophets have spoken on the importance of sleep, and cited the Doctrine and Covenants scripture and a story about how President Marion G. Romney was counseled by another Apostle to get enough sleep so Pres. Romney would be more able to receive revelation.

Which bring me to wonder - has any other prophet spoken out on how important sleep is? I couldn't find a conference talk or anything else.

I don't know about that one; sleep is hallucinogenic, addictive, the withdrawal is awful, and it interferes with time we could use for more productive things.

There is an article in the July issue of the Ensign magazine about this as well. It also mentions the Romney story and the D&C scripture but also has some others with references at the end.
