Nothing to be scared of. One day at time is fine.
FWIW I am more scared what I could lose if I continued drinking. Thoses negative thoughts about what I could lose do stop me from drinking. Take comfort from the fact no matter how hard that you are now stopping a "train wreck" from happening in the future. Picture yourself 10 years down the line still drinking......will you have kids? Will your kids see you drunk? Will your husband look on you as a wonderful mother? The list is endless.
