'I couldn't function without alcohol'

Nuala McCormick, 35, started drinking when she was a teenager.

"I was very painfully shy growing up and therefore alcohol to me was the answer to that, I thought I needed drink to fit in," she said.

"I was like Jekyll and Hyde. I was a quiet person without alcohol but as soon as it hit my system I became aggressive and a nasty person to be around."

By the time Nuala was working as a musician in her 20s she was drinking every day.
