Days off are going to have to be redefined. At the moment they are meant to be days when you can do what you like, relax away from work, etc. but when you finish late, have 2 days off, then start early, you cannot go out with friends for the evening and have any drinks at all.
I'm not saying that alcohol is a necessity just that the rules and rosters are getting to the point where airlines rule your entire life, and there is no "time off" in reality.
I do not condone anyone going out and getting plastered the night before an early report.
But if the CAA should say that 1/4 of the drink drive limit is the maximum for aircrew over here, then they should provide rules "for the avoidance of fatigue" that mean you never fly with a fatigue level that is equivalen to 1/4 of the drink drive level.
But it doesn't happen.
So to all those observers out there who are telling aircrew not to drink, could you instead start lobbying the CAA to provide rules on fatigue that protect the passengers too?
