Glad to have you here, you'll find a lot of support.
At the end of my drinking days I drank at home alone, too. No one to answer to, no one to see how much I drank and no one there to see the pitiful mess I was the next day.
It wasn't much of an existence. And that's all I was doing- existing.
Having some sober time behind me now, I've found a whole new world. Sober.
I wish the same for you, and best to you.
