There's no way on telling if you are already get addicted or not until you would be able to realize that you have losing money too much and this is in fact reality. There are really just that those people who are really that good when it comes to their discipline and control when it comes to their fund handling and there are ones who do really suck at this and this is why they do really end up on such disaster.
You wont really be getting addicted if you are really just that sensible on what you are doing and really having those kind of limits on the time that you do gamble.
You wouldn't really be needing any help or whatsoever but if it happens that you are already that having that kind of problem then self will should be enough
but commonly people do fail at this.
Really, i dont totally agree with you on the inability of the addictis to know when their slide into the addictions and from my experience of how addictions manifest and grow is a process that the victim himself build up over time until he gets to a point where he can no longer control the urge and tendency to keep getting my of the addictions.
Just take it as one who usually palyed for just a 3 hours a day, and suddenly he starts going in for longer periond of time let say spending 6 hours at that point, he ahould already know that he is sliding gradually into addictions.
Its good that we are seeing independent efforts to helping gambling addicts overcome their addiction in a professional way.
