caught drink driving - help

[driver1]

I was at the pub, i'd had around 4 pints to drink I had an argument with the missus, knew I would be over, so I waited an hour, set off home which was around 2 miles from the pub, got pulled over just as I got onto my road. I blew 42 at the road side and 41 at the station.

I'm preparing for the worst as I really don't think I'm going to get off, so need to know what the worst case scenario is going to be?

Thanks for any advice given.

The laws of driving under the influence vary between countries. One difference is the acceptable limit of blood alcohol content before a person is charged with a crime.
