London, June 3 (IANS) Actress Olivia Wilde has revealed that she secretly battled weight and sleep issues after her marriage broke up last year.

The Tron: Legacy star admits she went through a manic phase and turned to food to self-medicate after initially losing weight during a battle with insomnia, reports contactmusic.com.

I lost a bunch of weight and I was really never sleeping... I moved in with a girlfriend and she said, 'You don't sleep; you sleep three hours a night!' Then you go through a period where you're self-medicating with something to fill a void because you have created a void by removing someone from you. There's a chunk missing and people fill it with all sorts of things, she told TV talk show presenter Amanda De Cadenet.

I'm a healthy person, but I definitely packed it on because I wanted to feel a buffer between me and the pain, because the world started getting really scary and new relationships (and) dating was a lot more painful than I ever imagined, she added.
