The amount of money I spend on gambling will largely depend on how much I need to cover my living expenses each month. Generally speaking, I never spend more than 10% of my total income on gambling each month. I know that doesn't seem like a lot. And, believe me, I'm not saying that 10% is a safe amount. The important thing is to consider the total cost of your gambling habit before you make a decision. The reason I don't want to risk more money on gambling is that, in case I lose, I'd have to cut back on some lifestyle expenses. And that is definitely not something I want to do.
