The pressure of running a small business has hit the health and personal lives of Britain's entrepreneurs.
A survey of 400 small business owners showed that many suffered from tension, anxiety, insomnia, and high blood pressure. And many drank and smoked too much and did not spend enough time with their family.
Half of those questioned by software firm MYOB spent up to three hours a week on accounts administration, with one in 20 toiling for more than eight hours to sort out their finances.
One in three said they updated their books every day, with a "worrying" six per cent leaving it until the end of each financial quarter.
The poll showed that one in eight small business owners had to wait three years before making a profit.
