I chose #1 because I was changed by the experience of drinking and recovery. I think I have a deeper sense of life and of wanting to be present and aware in each moment.
I could easily make an argument for #2 or #3. (I'm rediscovering my authentic true being; or I'm essentially the same, just with a few more experiences in life, which is part of life.)
Great survey. I found it so interesting to read what others wrote.
