When I was a JW I was a liar and greedy -- I drank but never got drunk.
When I first left, I drank, smoked, fornicated, and swore but no more lieing. I up front and honest about who I was and what I was doing.
Then I found myself enjoying being nice to people. The greed disappeared. Then the drinking stopped because I decided that I really just didn't like it all that much. I've been "out" twice in a year and each time I had a couple of drinks and not even a buzz.
The fornication changed to one person instead of whoever randomly caught my attention. I'll be getting married in June then we can say that the fornication is gone. I'm still smoking -- I don't know when I'll get around to trying to quit.
I am a much nicer, friendlier person now. Overall much more moral too.
