It is not easy at all to stop gambling. I don't speak for myself, but there have been plenty of people who have tried to quit gambling and failed. And that is often accompanied by large losses on the bank roll. I think it's very difficult on your own. Cold Turkey seems to me to be the only and best way, because phasing out is a very expensive process and the decay remains present that way. Rehab could also help, but the risk of relapse is high.
