Oh my.
That is such a terrible time you are going through.
Medical advice from non-doctors can be really dangerous, which is why it's not allowed on this site.
Detoxing from three pints of vodka is kinda heavy duty, so prepare yourself for a rough few days.
I would totally agree with the suggestion that you go to an ER.
Cold turkey withdrawal can be fatal.
I really wish you and your daughter well.
Please use this site, as it was a great source of support for me in the early days and continues to be today.
