Worn-out workers admit much of their morning commute is carried out in a 'zombie state', a survey suggests.
Despite setting their alarms for 6.30am and leaving the house by 7.23am, most Britons don't feel fully awake and able to function until 9.40am on the average weekday.
More than 60 per cent of commuters admit they often arrive at work with no memory of the journey.
And 54 per cent can be found sitting at their desks with a glazed expression long after they have entered the office.
Nine in ten of those questioned in the Quaker Oats survey of 2,000 employees admitted they operate in a 'zombie state' most mornings.
