Heath Ledger's sleeping pill 'controversial

The sleeping pills Heath Ledger was reportedly taking have been embroiled in controversy in Australia, where hundreds have had bizarre and potentially dangerous reactions to the drug.

Called Ambien in the US, the tablet is marketed as Stilnox in Australia.

It hit headlines last year when a national drug hotline fielded calls from users reporting strange side-effects.

Some 500 people described odd behaviours from walking, crashing cars, having sex and falling from balconies after popping a pill.

One patient gained 23 kilograms over seven months after unknowingly eating from the refrigerator while asleep.

Another patient woke up with a paintbrush in her hand after painting the front door.
