This is great and I wish I had it a few years ago when I first tried to get sober. I made the mistake of continuing to hang out with the same people and go to the same places where I used to drink.
This time I made drastic changes, and went as far as deleting the names and numbers of people who were dangerous to my sobriety from my phone and Facebook. I have been sober since 3/31/14.
What ever it takes!
