#6: Kelsey Grammer Struggled Quietly Behind the Bar in the Final Season
During the last season of Cheers, Kelsey Grammer’s alcoholism became impossible for his co-stars to ignore. They noticed he was unusually withdrawn, tough to work with, and sometimes nearly catatonic between takes. The sharp, witty Frasier Crane everyone knew wasn’t always there off-camera.

The cast and crew tried multiple interventions until Grammer finally agreed to seek help. His recovery wasn’t immediate — he has said that he didn’t truly stabilize until the early Frasier years. It was a rough chapter behind one of TV’s most polished characters, handled with real care by those around him.
