There are numerous behavioral problems that an adult can have, and some of them may even be more than just behavioural. First, it’s important to understand the difference. If you have an addiction problem, studies have shown that this is more like a brain disorder, and actual illness, rather than a behavioural problem.
Behaviors aren’t always easy to let go of, and some of them are technically still in line with addiction. Once you cut your addiction to something, you still need to try to change the behaviours that go along with that addiction; like putting a cigarette in your mouth, or snacking when you are bored.
