Welcome to SR. I had to keep busy on weekends. I made plans and back up plans. And I check in often, OFTEN on the weekenders support thread here where I've got to know people and found a sense of accountability.
It's awesome not having hangovers. And my bright tomato red face is no longer red. My dad always said he knew when I'd been drinking by my skin. He hasn't had to say that for a while now.
You can do it.
