CrossBars post on the Swedish regulations is interesting as being a regular visitor to Sweden I've always thought their rules to be almost unworkable under UK law. One would have thought that to establish that one was over the 0.2 promille limit 8 hours before flight you would have to be tested. Were you over the limit you could then say that you had no intention of flying the next day and were about to call in sick when they busted you. I can't see how you could be charged with a crime you've yet to commit. Perhaps Flying Lawyer could give us an expert opinion? Has anyone ever been charged in Sweden with being over the limit 8 hours before but not at the time of flight?
The figures CB quotes for a bottle of wine taking about 9 hours to clear are equally interesting. Working on the average bottle of wine being 750ml at 12.5% alcohol then I reckon 9 hours should also do you for about 4.5 pints of weak UK beer (3.7%) or 3.3 pints of continental angry juice (5%), which rather shoots down the argument of the people who say only 1 or 2 drinks are acceptable on a nightstop.
