The only way to quit gambling for good is to eject it from your everyday life, dont think you can control it, that is just an illusion, forget about it, stop gambling and begin to do other stuff to entertain you.
It is very hard to do that,trust me because I have done this. I couldnt stop thinking about it and I have done alot of things to make me forget about it but I just cant control myself. I only play for fun right now to satisfy myself however in reality I almost spend nothing for this because the amount for bankroll is very small
