I guess almost every gamble addicts at some point becomes aware that their behavior towards gambling has gradually changed over a period of time, but the problem here is that they don't know how to get themselves out or finds it difficult to start drawing themselves back; hence it becomes important for such category of gamblers to go check him or herself.
Taking you for instance, in my trading perspective, there was a time in my early stage of trading when I started over-trading, I knew about it but reducing the rate at which I trade becomes challenging, and it took me some time before I figure out how to reduce trading frequently.
The mindset that is wrong from the start will make them addicted to gambling and indeed when addicted to gambling it is difficult to recover quickly, some even say that for those who are addicted to recover they must ask for help from a psychologist. It is true that the problem is with their thinking but in my opinion even with psychological help it does not guarantee that they will recover quickly because this is more directed at how they themselves are with whether or not they will be aware to stop or reduce their gambling activities.
We know that gambling addiction is difficult to cure, almost the same as drug addiction. However, maybe drug addiction can still be cured with certainty because there are rehabilitation centers but I have never heard of a rehabilitation center for gambling addicts and it is impossible for a rehabilitation center to accept those who have problems with gambling addiction.
