Florence Welch only has a "blowout" occasionally nowadays.

The Florence + the Machine star no longer drinks alcohol while on tour as she doesn't think it's conducive to good shows. However, when at home it's a different story.

"When I'm on tour I'm really strict with myself. But when I get back to London I still go a bit crazy. My sister will say, Where have you been for the last couple of days?' and I'll have been going out seeing friends. But that's only a blowout now and then, everyone has their moments. I'm still trying to figure out the balance. I'm still learning the best for me. I haven't figured everything out yet," she explained.

Florence, 25, grew up following punk bands and when she hit the big time she tried to emulate them. That meant drinking a lot, especially when she saw many other modern groups behaving in that way.

She eventually decided to stop after worrying things had gone too far.

"I used alcohol to give me confidence on stage. Now I feel more comfortable with my music, I find confidence in that, but it took a while to get used to that," she told Look magazine. "At the level I was going, I don't think I could have kept it up. I couldn't carry on like that. I realise people had paid to come and see me and it had to stop."
