The relapse starts with the thought and if we can catch that thought and see what is behind it we can do something to stop the gamble in its tracks.
I learnt to notice when I was thinking about gambling and then think – what has caused this and how can I satisfy the need in me (usually an emotional one) without gambling.
For me it was often simple boredom. Gambling created drama in my life and made life more interesting . But it was negatively interesting – so finding stuff that was more positive was the way out for me.
Find out emotional need you are trying to satisfy with gambling and try another way . I wish you well.
