Very sorry for your loss!!
Obviously it depends on the person, if someone is new to SR after years of drinking or in a bad way coming off a 3 week binge that person would be best seeking medical treatment.
However the person who has relapsed for the 4th time with weeks in between of Sobriety, an early night and some fluids/food, whilst pouring the rest out, will steady the ship.
Very sad nonetheless, a reminder that alcohol is a serious business!!
