Geez, it sounds like you are working a really dedicated and thorough program to me. I'm only 50 days into sobriety and I can make just 3-4 meetings a week max. I have a similar schedule to yours, single mom with 2 children and a 50-60 hour work week, a commute, housework, cooking, laundry, and now NA. Do what you can. Believe it or not, I think being a busy person actually helps keep me out of trouble. I don't even have time to miss the drugs now! I do have to make time to think about the steps though. I've been using my commute to do some work while I drive (radio and phone off). Give yourself a break, you don't have to do it all in one week!!! Seriously, it sounds like you are really doing well, how are you feeling inside? That's what's really important. Do you feel like you are progressing to your satisfaction?
