Dave Ramsey's advice is dangerous and unprofitable. His advice is based upon the belief that debtors can never again be trusted to use credit. Fortunately, he is wrong, because people almost always can change their mindsets. It just takes commitment and the right tools. It took me years of living on cash and debit, but I developed the discipline to use credit responsibly. Maybe you can do it faster?
The key to successful use of credit is to use it as a payment tool, and nothing more. If you're not yet ready to do that, freeze your credit cards in a block of ice and let them chill for a few months while you live on cash/debit. When you're ready, thaw them out and start using credit as a payment tool. Don't look at it as a way to access someone else's money, but simply as a way to access your own money. Once you use it, it's gone. It's no different than a debit card or the green stuff. In fact, you might want to rotate your payments through cash, check, debit, and credit, so they all have the same feel. When you can treat $100 of credit the same way you treat $100 of cash in hand, you have beaten the credit card trap.
Here's another idea to reign in credit spending: Keep two accounts at your bank. One of them is for you, the other is for the credit cards. At the end of the day, add up everything you charged on the card and transfer that amount from your account to the credit card account. This serves two purposes. First, it makes credit card use hurt. Every time you use it, your account gets a little lighter. Second, it guarantees you'll have enough to pay the bill at the end of the month, because you've already transferred the entire balance into "their" account. When the bill is due, all you have to do is use your bank's billpay or your credit card's webpay to transfer the contents of the credit card account to the actual credit card issuer. (You get to keep whatever interest was earned in the "credit card" account. This time around, THEY will be paying YOU interest.) If it helps, you can pay the card issuers more than once a month. That way there will be less temptation to dip into your credit card account.
It may help to approach spending like a dieter. Instead of counting calories, you're going to be counting pennies. Decide how much you're going to spend on credit in a given month. Deposit that sum in the bank. Carry a check register with you and, every time you use the credit card, deduct that amount from the balance in the register. Dieters rarely realize how many calories they eat until they start counting; that's how they got overweight in the first place. Is the same thing true for credit card debt? I believe creditaholics and overspenders can benefit by recalculating their bank balance every time they spend something. It will help you cut the fat out of your diet, and make you think twice before you buy the metaphorical Twinkie.
As you interact more with your money and see how it flows, you will develop control of it and a sense of responsibility that you might not have had before. You'll feel every dollar leaving your possession, and you'll start finding ways to hold on to those dollars longer.
