Lorraine O'Loughlin, 28, an obese mum-of-three who weighed 120 kg lost 43 kg after she quit drinking coffee 15 times a day. She picked up this bad habit after she fell into depression and stopped leaving the house almost completely. She had this unhealthy routine where she skipped meals in the day and then binged on chips and chocolate at night. And as she had an insomnia, she found a solution to help her go through the day – 15 cups of coffee with three sugars each.
