Thank you, Christian. It was a number of years ago, early in my sobriety, that I had the thought, 'If God did allow some of us to go back and alter the past, those that did so most frequently would be those most lost to addictions.' The more opportunities to undo what we object to, the bigger the mess we would make. 
"My thinking is not your thinking, your ways are not my ways." This fits me to a tee.
