A Blenheim woman who drank 18 litres a day of Coca-Cola says she didn't worry about her addiction, until her health deteriorated.
A coroner's report into the death of Invercargill woman Natasha Harris has found she most likely died from drinking too much Coke - her regime was up to 10 litres a day.
Former coke addict Paulette Wyatt told Newstalk ZB's Mike Hosking that at the height of her addiction, she hardly ate, and her weight went up to nearly 200 kilograms.
She says it didn't worry her until she saw a doctor.
"My heart started pulsating and stuff like that, so that's when the doctor said 'you probably shouldn't be drinking Coke that much', so I cut it right back.
"I tipped it all down the sink and stopped."
Paulette Wyatt says it was a very easy trap to fall into because the caffeine was very addictive.
