The best way would be to force yourself to stop. Withdraw your entire balance from any gambling sites, block those websites, do not use the Internet for a long time. This can be very hard and requires someone with a large amount of self control. But then again, when you have 1-100 million satoshis, it can be quite tempting to play with it.
I did it already many times and it goes failed, I always come back make deposit after I have pulled out all my money from gambling account. Self control are easy said than done, everything messed up when you are suffering in lost, and it's just happening to me, leaving or even stay away from gambling are hard thing to do.
