Awesome job so far, Hez! Keep it up. I agree that long-term sobriety will require you to do this for YOU, but knowing how and why it will benefit your kids can still be for you. My kids are really proud to have a sober dad and I am incredibly happy and proud that I am altering the way things have been in my family for generations, where kid watches parents drink and over-drink for his/her entire childhood. Instead, while trying not to be preachy, I can talk to my kids about the dangers of alcohol and, at least to some extent, why their father no longer drinks.
Keep up the good work!
