Nothing Trumps a good night's sleep but new job's a wake-up call
Donald Trump says he's working "long hours" and frequently only gets about four or five hours of sleep a night.
The US president told Fox News' The O'Reilly Factor that he typically works until midnight or 1am, then wakes up at 5am to eat, read newspapers and check the television.
Mr Trump said that at the start of his presidency he has been surprised by "the size, the magnitude of everything" and being president can be a "surreal experience in a certain way".
But he added: "You have to get over it because there's so much work to be done."
