Survivor New Zealand host Matt Chisholm has opened up about his 20-year battle with drinking, saying he would sometimes "black out for hours" and wake up in different towns.
Speaking to Woman's Day, Chisholm says the problem began as a teenager when he discovered he struggled to hold back when drinking.
"When it came to getting on the piss, I had my dad's DNA – it was either none or 100. If I could remember what happened after 10pm on a night out, I was doing well.
"Normally, I would black out for hours and sometimes wake up in another town with no recollection of how I got there or what I'd done."
Chisholm says he tried to give up at 24 when he had to care for his brother who had suffered from a series of strokes, but eventually began drinking again when he went overseas at 27.
He says he woke up after a week-long bender in 2010 and gave alcohol up for good.
"I knew I was done and would never, ever look back… I just made a decision my life was better off without alcohol."
