I was pretty confident the first time around as well.
It didn't seem to hurt me.... at first.
It was when I got confident enough that I just stopped going to meetings, stopped posting on here, stopped thinking about "recovery" really at all that the trouble came.
Not long after that shift, I began feeling quite confident that I could drink in moderation.
Which resulted in a 1.5 year bender.
This time around, I am positive, I am hopeful, I am even - dare to say - confident.... but I am not willing to become complacent in my confidence. I read enough newcomer stories and reflect upon my own history just enough to keep an edge of uncertainty present. Just this side of confidence enough to be smart enough to remain wary.
Confidence is OK.... but take care that it is balanced with actual active effort and prudence.
