go from one extreme to another

go from one extreme to another

To change or shift between two very different states or things. A: "Why's Mom so upset? I thought she was happy that I moved out." B: "Yeah, well, you know Mom—she tends to go from one extreme to another." Snow one day and 60 degree sunshine the next? Boy, the weather around here sure can go from one extreme to another!
