Hey Alan,
When your in the midst of addiction, the temptation to go play “just a bit” it sometimes undeniable. You’ll need some help and I highly recommend for you to self-exclude yourself from all venues where you normally gamble. If you do any online gambling you can install a betting blocker such as betfilter or gamblocker (both are great, and don’t mess with your computer or deny you access to anything else other than sports betting/casinos/poker/pokies sites – you can still visit gambling recovery forums don’t worry).
It’ll help you get through that initial period and after the weeks and months go by, things will get a lot easier. Without a doubt you’ll continue getting urges every now and then but you’ll learn more about yourself and your triggers and how to deal with them better over time, until YOU are the one in control and not the addiction.
Just remember that it’s a lifelong journey and the battle is never over, you might continuously actively fight the addiction until you can control it. You can overcome it but never get complacent because inside all of us is a compulsive gambler just waiting to burst out. Never give it a chance to come back.
