I gave up so many things. It wasn't that I was out of control - it was just years of eating anything I wanted. I wouldn't eat a whole pizza, but if I wanted pizza two or three times a week, I didn't think to limit myself. So I just cut out all the stuff that I viewed as unhealthy.
I published, privately, a collection of my serious poetry I had written over the years. I only published 50 copies, which I gave to friends, in a special deluxe edition. It was ridiculously expensive but I'm glad that I did it.
