One more thing, InquireWithin,
You should be very proud of yourself for not just walking away from this. You are wishing and hoping that your wife will suddenly "wake up" and understand she can't continue her behaviors. But she can't. One sip of the booze, and her "off" switch is broken. She is out of control, and like a child throwing a tantrum, she may be actually relieved if you take control of the situation and remove her choices from her. You may have to enter into some type of conservatorship with the help of your attorney so that she cannot continue to make these choices while she has the ability to harm herself and her children. There are ways. If necessary, look up the "pro bono" services offered by your State Bar Association. They all have them, which offers free services if you need to do it that way. CPS may need to become involved, but your lawyer will tell you about that.
If you need help, please please ask.
