A fresh start
Congratulations on your decision to stop poisoning yourself. Take the time to detox and try to avoid situations that might cause you to revert to your old ways.
I would like to suggest that you take a serious look at your friendships and honestly evaluate each of them. Are these people 'drinking buddies' or true friends?
It's not easy to walk away from people you consider friends but your health and well being need to be your #1 priority now. In time, once you are confident in your sobriety, you may realize that your idea of what a true friend is has changed.
Good Luck!
