Very good question. When I first had the surgery, I would say, "I'm still the same, just weigh less". But, now at almost 7 month out and near goal, I know that is not true.
There is a "lightness" (no pun intended) about me. I'm happier. I don't worry as much. I don't agonize over problems. I'm proud that I faced a decision and triumphed. I don't mean that I triumphed by losing a lot of weight. I trumphed in that I decided as it says on top of this forum. . . it's time to be healthy and I did something about it!
I've gone back school and will be trying to enter an LVN program in a couple of years. I decided that I wanted my work to be something I enjoyed, not just a paycheck.
Now, some of these changes I believe are due to my "advancing"

age. But, my surgery and the aftermath have changed me forever.
