Hi Nuleaf. Like many, controlled drinking for me was just an excuse to keep drinking. I even had a boss (a sociologist- so he adamantly believed logic can overcome addiction- so controlled drinking was what I had to do). That made it worse- I had official sanction to drink, so when (and it came) I stuffed up- I could say 'I am trying'. I hope you figure out what works for you.
To me- you saying binge drinking, worry and job security are huge red flags. I am glad you are looking into it seriously with a plan in mind.
