Britney Spears reportedly took over 100 pills during a massive 36-hour drugs binge last week, before being hospitalized.

The troubled singer is said to have washed down the huge amount of drugs with a 'Purple Monster' cocktail - a mixture of vodka, anti-flu syrup and an energy drink, before being taken to Los Angeles' Cedars-Sinai Medical Center on Thursday night, according to Britain's Daily Mirror newspaper.

Her hospital dash came after she refused to give her sons, two-year-old Sean Preston and one-year-old Jayden James, back to ex-husband Kevin Federline after a custodial visit.

A source close to the singer said: "She ended up taking 20 Clenbuterol diet pills, 18 herbal speed tablets, 18 Piriton anti-histamine tablets, 12 Vicodin painkillers, 10 sleeping pills and eight antacid reflux tablets.

"She also drank one bottle of Pepto-Bismol, two bottles of NyQuil and two bottles of OxyContin painkiller, and took a further 10 anti-hangover drugs and six Ritalin tablets which are usually used to treat Attention Deficit Disorder (ADD)."

Meanwhile, Britney's estranged father Jamie reportedly "broke down in tears" when he visited his 25-year-old daughter in hospital.

A source told People magazine: "Jamie was incredibly upset. He broke down in tears. When he realized the situation, it just literally broke him down.

"Jamie thought he understood what was going on, as he was the only Spears family member there during Britney's mental evaluation.

But it's got to the point where he doesn't know what to do. "Everyone is trying to figure out the best thing to do, but who knows what that is now."

Britney left hospital on Saturday (05.01.08), after being held for a psychiatric assessment.
