I'm just sharing my personal preference and not trying to tell people how to live their lives. I don't like personally like the idea that I'll only be healthy if I take this drug for the rest of my life when I could (again - speaking for me), be more disciplined about the food I put into my body.
“be more disciplined” - did you read any studies about the sources of obesity? Or do you struggle with weight since childhood yourself?
Why this has to be all or nothing?
You can use the drug to loose weight while trying to understand the underlying problem.
