Cranberries singer Dolores O’Riordan has revealed the extent of her personal problems at the height of the band's fame and says she "hit rock bottom" and almost went insane.

The Limerick band were catapulted to global fame in 1993 and enjoyed a string of hits throughout the '90s. But the pressure of constant touring and promotion took its toll on O'Riordan. She recently revealed she underwent therapy to cope, and now she's talked about how she almost lost her mind but was saved by having a baby with her husband.

"By the third Cranberries album I started to lose the plot," she told The Daily Telegraph. "We'd signed up to tour for two years straight, and I can't remember much of that time because it was all about getting up early, working, working, working, and then trying to catch some sleep before getting up again. Soon enough I hit rock bottom.

"I thought the best thing to do to bring me back to reality would be to have a child, and by the time I had my first, Taylor, when I was 25, we'd sold 35 million records as a band and I'd had enough; I knew my sanity was more important than success."

The Cranberries release their comeback album Roses shortly.
