Over the limit
Someone already mentioned the Nortwest 727 crew that flew drunk from Fargo to Minneapolis. Uneventful flight, but they were drunker than the AWA guys. So, it is not an automatic accident when the crew is drunk.
I personally believe it is unforgivable to show up toasted to fly. Passengers need to respect us as a profession, but every time this things happen unrepairable harm is done.
I love beer, but I love flying more. It is not that hard of a decision to stay away from it when I am working.
As a side note, body size has little to do with how much you can drink. I have friends that are small that can drink my arse under the table.( I am 230 lbs and feel the effects of 3 beers)
Cheers, with responsibility.
