Ellie Goulding's battle with insomnia: Singer's 'body clock is completely out of sync'

Ellie Goulding is having a hard time to have a proper sleep.

British singer/songwriter Ellie Goulding is reportedly suffering from insomnia. The 29-year-old singer had cancelled several tour dates of her Delirium Tour because of exhaustion.

A source told The Sun: "Ellie's body clock is completely out of sync and she has found herself lying awake in bed most nights unable to get to sleep."

"All the travelling through random time zones has messed with her system. She just can't get to sleep at night, and even when she's back in England the insomnia is sapping her energy. She's worried about it as she doesn't want to be tired before going on stage. She's a professional and wants to give her fans the best performances possible," the insider added.

During an interview with Red Magazine, the Love Me Like You Do singer had talked about her hectic schedule. She said: "I had to pay for me and the band to have IV vitamin drips. Can you believe it? Backstage at Alan Carr and we're all sat there on drips. The last month has been really testing, on everything, on my sanity. The music industry isn't like other industries – there are no rules about working hours, or taking breaks. A working day will start with a 4am flight and finish at 3am the next day."

"Sometimes I don't have time to eat in the day. I go, are we gonna get lunch? And everyone around me is like... [sharp intake of breath that signifies "No".] But, even when you've made the money, people still want to do the thing they love. I know in my heart that if I stopped doing this I would probably get depressed. I'd end up very free – but very miserable," she revealed.
