Thank you for your input and comments. It helps to hear from others that we are not alone in this.
I do realise how hard this is for an addict to even think about beating it. Every day, every time you turn on the TV in the evening, the computer any time, your mobile etc etc, you are bombarded with adverts for slots, poker, football, horses etc etc.
The people/companies that make such vast profits from gambling salve their own consciences by contributing a tiny sum from their profits to the charities and organisations that support the addict, compared to the huge amount of money that they take every day from the people they profess to be helping. To my mind, their efforts are shambolic. It should be the easiest thing to do, on their websites, to block yourself and it should be the hardest thing to do on their websites to unblock yourself once you have done it.
Yes it has to come from the addict , the CG, but it seems to me that the casinos etc recognise the ability of the CG to forget past losses and use that to keep them playing.
