"Gambling is one of the finest things a man can do, IF he is good at it" - Krusty the clown's agent
I have friends in the same boat, My honest advice, Don't fight it, You will do well for a while, And lack of rolling the dice will send you into a frenzy, Work out what you have coming in, Work out what you need to survive (Inc debt repayment) Sell any assets you can live without (be harsh on yourself) Then the rest, Gamble small and control yourself. "quitters never quit" is my line here.
This could probably go either way. No gambling eventually gets you depressed and thinking about all the money could could be winning. If you gamble a little, then it reminds you that it's not so easy to double up, but then there's the temptation to try to win back what you lost.
However, I agree that putting say $20 a month to it may work. It's enough to keep you realizing that it's not so easy to just win your way to millions, but if you go into it saying that it's going to be a loss then you might not get the urge to try to win it back. I'm not really sure though as I've never been addicted to gambling. It kind of sounds like "smoke only 3 cigarettes" which doesn't seem feasible to me either.
