"It turns out, you're not alone. We've heard from people that they want more options to determine what they see in News Feed and when they see it.
"With Snooze, you don't have to unfollow or unfriend permanently, rather just stop seeing someone's posts for a short period of time."
To take a 30-day hiatus from your oversharing friend, you will have to click on the menu icon at the top right-hand corner of a post and select "snooze" from the drop-down menu.
If you're looking for a more permanent solution, you can also unfollow friends, or hide or report individual posts in this way.
