BBC Breakfast presenter Susanna Reid says Strictly Come Dancing is ruining her sleep.
Susanna's performance on this weekend's BBC1 show delighted the judges, putting her near the top of the leaderboard.
But she told the Radio Times: "I dream of sleep. I'm used to going to bed late, often after Newsnight, and then getting up at 4.30am to go to the Breakfast studio.
"But my few hours sleep are now punctuated by panicky starts as I wake and go through my steps horizontally.
"They say you're really learning a language when you start to dream in it. The trouble is, I'm still awake and dancing perfectly is just a dream... A sleep-deprived brain finds it hard to learn."
Susanna, 42, said she also had blisters, but not from any fancy footwork.
"They're not from training, they come from ordinary new shoes that don't quite fit, but which I insisted on buying a week before our first live show and wearing for a whole day.
"My mother was with me and said 'For an intelligent woman, you make some foolish choices!'," she said.
