Britney Spears was prescribed Prozac-used for depression and panic attacks-at the age of 18.
The singer, who rose to stardom in her teens, had stunning looks, bags of talent, a multi-million dollar fortune, and worldwide fame.
But, when it came to her personal life, she was a nervous wreck and was on Prozac at the tender age of 18 years.
During the European leg of her 'Oops! I Did It Again' tour in the winter of 2000, Britney started having "massive anxieties" in the middle of the night.
"She had trouble sleeping and crying fits. She was restless and agitated. Nights were the only times she was alone and she struggled with that... When nothing was happening, it drove her crazy. Only exhaustion would knock her out," the Mirror quoted a source close to Britney as saying.
Her anxiety was not drug-induced, but was her natural state, which got further aggravated by fame.
Britney's moods noticeably started swinging- high and happy one minute, sad and brooding the next.
And thus, the 'Womaniser' star was prescribed Prozac.
However, she treated it like headache tablets, and took a pill only on the days she awoke depressed-this seemed to make her more hyper.
