Hi loulou, I'm in the same boat (although we don't have kids). This will be my first Christmas sober. I don't know if this will help you, but I will share how I am approaching it. I've done Christmas drunk...a lot. I know what its like. Sometimes it has been a lot of fun, but it has been an embarrassing disaster as well. By being sober on Christmas I have one guarantee, it won't be an embarrassing disaster. I think your kids are going to really love you for it.
