I was caught in a similar situation (although a more emotional and violent, long story). I admitted it, was breathalysed at the station twice over the limit and was banned for 9 months (12 months but reduced with a course). They said I could have said I wasn't driving and the state of the witnesses could have meant I may have got away with it, but such is life. You do wrong, you take it on the chin and move on. I am however still puzzled. If I had refused to give a sample of breath or blood, I would have been banned for 6 months for that offence instead like the story in the OP? Doesn't seem right.
