I find I'm far more capable now than I was a drinker. My problem has been finding balance...I played hard so I worked hard too...when I quit drinking, I forgot all about play for a few years....
I think initially I was scared if I had too much downtimes I'd drink...even when that fear went away, the habit was ingrained and I very rarely goofed off.
For the past couple of years I've been working on finding the mid point - a healthy work/play balance. I think I'm better for it
