Hang in there squishy. Each day is important.
So much of what children remember is generalized. They are really young and there is plenty of time to make sure they remember you the way you want to be remembered.
If I was you I would establish a really firm dinner routine and never falter. Also, never drink before dinner. Then you have put it off. I too used to drink on hitting the door. Then it was effectively over. So, if you are just in the stopping stage, and you are working with a husband who isn't really "on the boat," just saying, "no drinks before dinner" puts it off. Then you can function in a positive way and keep pushing back.
I need to research that wisdom we have all heard about breaking and making habits. I'm currently doing both and if I can do it, you can do it. And you have those kids to think of. That's motivation.
