Welcome to SR, lots of good advice above, and sounds like you have already started by apologizing at work, nicely done!
I have been on and off her for a few years, and had a few stretches of sobriety, however, once I had some time under my belt I started to think "What is the harm in one glass of wine..." I made the decision to make 2016 my first of many sober years, and with the help of SR and sticking to a plan I am on day 39 today.
Would love to have you along on this journey! Spend some time reading and posting, and also check out Dee's link about having a plan, that has been crucial for me to stick with my decision.
❤️Delilah
