Frank, Im afraid I wasn't clear with my questions:

Originally I wrote:

Frank, a question: does an addicted gambler who has the restraint/discipline to limit his gambling to one bet still an addict?

Another question: does an addicted gambler who has the restraint/discipline to limit his gambling to a win goal/loss limit still an addict?

Allow me to revise the questions:

Once a gambler who is diagnosed as an addict develops the restraint/discipline to limit his action to one bet is he still an addict?

And the revised second question: does a diagnosed addicted gamblers who has the restraint/discipline to limit his gambling to meet a win goal/loss limit still an addict?
