What do you do?

What do you do when your life goes through a transition and you wake up one day, nothing is the same, and you wonder what just happened? When going out to bars was 'the thing' to do on the weekend. How do you transition to something more wholesome? It's inevitable and deep down you know it, though you don't know how to transition slowly. All is not gone or lost, actually quite the opposite. You are starting to really live. Priorities change and it will be wonderful, but what to do in the meantime?
