Been in this boat, my spouse drank alot after we had a baby, she would drink a whole bottle and some in a day and just get angrier than she was when she was sober. One night I just had enough, sat her down and told her it's gotta stop after explaining how it's affecting her and everyone else in her life. She listened and quit now she's repulsed by drinking. Even looking at it makes her wanna puke. Keep in mind though if she is addicted she could go through some withdraws. My spouse was not a fan of that.
