Welcome to SR.
I feel for you, I really do. You are doing this to yourself.
You buy the bottle, you pour it, you pick up the glass and pour it in your mouth. You. No one else, not some "other part" of you.
Take the responsibility to fix this before you lose everything. Make no mistake, you will lose everything.
Your babies will be fine with a sitter while you get help. Many AA meetings - especially women's meetings - either allow children or have babysitting on the premises. Call your local AA phone number. I love it when kids come to meetings.
You aren't being a great mom to them while drinking.
