There was an original thread on this story which was eventually locked but today a BA 777 First Officer was told he faces jail for reporting for a flight whilst over the legal drink-fly limit. Details are here:

What surprises me is not the 86mg reading, (which was over the 80mg drink-drive limit never mind the 20mg aviation one) but that the individual concerned claimed he had only had a single vodka and coke 8 hours before.
I cannot for a minute believe this to be true as this would have surely exited the system in entirety around 2 hours later? It is incomprehensible that he would still be so far over the limit 8 hours later. I would be interested in any views on this particular point.
