As for changing routine, I'm going to start attending church with my daughters and get more involved in the woman's bible study and sunday school class.
I'm also planning more activities with my closest friends, none of who drink. (I was bright enough to pick sober friends at least)
One thing that has been shifting lately is an overwhelming desire to be closer to God. I shut that part of my life out for so long and it made me miserable. I don't agree with some of the aspects of organized religion. But the foundational stuff, I do realize I need.
