Many may not realize that they are waking up blowing over .02 BAC. The culture is wrong to make you feel like a criminal if you do, I believe the airlines would be afraid of just how many delays they would have up front if they just made all flight crew blow before each flight. They should provide compassionate assistance to those who can not manage their lives and want assistance. Most airlines under FAA rule have a 0 tolerance rule, .02 you get benched and could probably plan on the airline aggressively doing "random" test's on you. .04 and you are done.
