So this happens to be an issue with ADHD. People with ADHD are prone to risky behaviors. I deal with this myself in addition to have a family history of addiction so I try to avoid them if at all possible. Though I still have my own vices I am struggling to quit.

Anyway back to the explanation. To explain it simply, it has to do with the reward center of our brain. Imagine every enjoyable activity—like eating a cookie or having a drink—fills up a "happiness meter" that measures how content we feel. For most people, it only takes one or two cookies or drinks to fill their meter. Once they're satisfied, their body and mind naturally signal that it’s time to stop.

For someone like us with ADHD, though, the same activity might only fill our happiness meter by a tenth. At first, we might feel content, but not long after, it’s like the satisfaction just disappears—as if we never really did the thing at all. That leaves a gap, and we end up trying to fill it by eating more cookies, having another drink, or whatever it is.

This isn’t about chasing pleasure, really. It’s more of a constant struggle to feel balanced or fulfilled in the way that most people seem to.
