Have you done any AA meetings? I was nervous about going to one, but was having a strong desire to drink, so I went. And now I've gone four times, and am making plans to go every day next week.
It has helped with reminding me I've got a problem, and keeping me on track. Try to go to one tomorrow, before the weekend starts. And maybe you can see if there are more meetings over the weekend you can duck out to. It'll help.
Congrats on making it this long! I know you don't want to throw it all away for one weekend, especially because you've said how important it is to get sober to be a better mom.
