Fandy, thanks for the great topic and I too am looking forward to what others have to say.
Here are some of the changes I've made:
1) Make my bed - well, almost every day!
2) Pack lunch for work - and keep healthy snacks there.
3) Call a friend every day.
4) Pray.
I rarely did these things when I was drinking which now seems really weird to me but at the time was NORMAL. I entirely forgot that these are things that many people do as a matter of course every day ... and I used to do. It feels really great to be getting parts of my life back again.
