Welcome back Noexcuse. Sounds like you are truly determined now. That's the way you need to be. Until I was 100% committed I didn't stand a chance.
Like you, I have young kids and drank through their early childhood. They were a huge motivating factor in my quitting drinking. I truly can't remember much of the 20+ years I spent drinking heavily.
First and foremost, do this for you... your kids and everyone else in your life will benefit from your efforts.
Time to find yourself again. You are on the right track.
Congratulations and lean on us as much as you need!
