Binge on chocolate sundaes

“you train yourself not to binge on chocolate sundaes or procrastinate any more”
Here, I’m totally lost. Could you explain what does it means?

…and Steve, thank you for your interesting post. I liked it very much.

People with poor self-control may over eat (binge) on sweets, like chocolate sundaes (ice cream), or constantly delay doing things (procrastinate). These are bad habits. I say that we can train our brains to stop indulging in these bad habits if we recognize that they are the result of a network of neurons in the brain that we can change.
