At the bottom of your screen (the black bar). Unless you're in monobook, in which case it's a tab at the top that says "Following". Click it when you're on a wall so it changes state to "Follow" instead of "Following."

or go here: Special:Watchlist/raw and manually remove listings you no longer want to follow.
