A New Zealand woman, fighting her addiction to the energy drink Red Bull, is suffering from severe withdrawal symptoms.
Brooke Robertson, a 23-year-old Auckland mother, says she lost 45kg in eight months by drinking nothing but Red Bull with a handful of dry cereal each day but now has ongoing health problems because of the diet.
Ms Robertson says her weight gain occurred while she was pregnant with her son Keir, now four and says she did not make a conscious decision to go on a Red Bull diet but found it was an appetite suppressant and as she was losing weight she continued to drink it.
The habit became an addiction which she hid from family and friends but it led to a minor heart attack and a two-week enforced stay in hospital. Ms Robertson says she suffered severe withdrawal symptoms such as sweating, nausea, and shaking and doctors realised she had an addiction, which has left her with a heart murmur, severe pain and cramping in her stomach and bowel and anxiety attacks.
A Red Bull spokesman said there was "scientific evidence that caffeine is not addictive" and the drink was available in 148 countries "because health authorities across the world have concluded that Red Bull is safe to consume" - but the drink is banned in Norway, Denmark and Uruguay because of health fears.
Last year research from both Australia and the United States questioned the safety of energy drinks such as Red Bull and suggested they could be harmful to some people.
