Starting here is a great step Magpie. You will need to hone in on your plan, but not drinking today is the most important thing you can do right now.
After a few days, I believe you will find that there are many things you can do after the kids are in bed! I was an evening binge drinker, and now I think of my sober evenings as the biggest gift of my sobriety. The things I accomplish in that space of time I wasted all these years!
Keep with it and you'll see. Guaranteed.
