Nancy Smith from Leigh-on-Sea, Essex, has suffered from flaky skin, lank hair and severe dehydration due to her addiction, but now claims that she is feeling better after kicking the habit, Metro.co.uk reported.
The 45-year-old mother of four said that she used to run around like a mad woman dashing here and there and cleaning the house after feeling energetic from the caffeinated beverage.
Smith's addiction to cola began at the age of 19, when her mother let her keep a big crate of Pepsi in her room.
Her habit affected her diet and she would mainly feed herself cocktail sausages, cheese and packets of biscuits.
Smith is currently off her compulsion and has taken part in an exercise programme to wean herself off Pepsi and lose weight.
