There’s a thread that will give you lots of ideas on how to get and stay sober. Please keep an open mind - having my mind made up and closed against certain solutions almost killed me.
I was a daily drinker and I drank for decades. But like you, once I started, I could not stop. And like you, I could not manage my behavior when I was drinking. I used several of the suggestions presented, some one at a time and some in combination with others. I’m sober and happy today.
Blessings on your house 
as you begin your journey.
