We didn't pay off our debt using Dave Ramsey, but we did have great success using similar techniques.
About 8 years ago, my company was starting to go through lay-offs. I took a look at our finances and realized that while we could afford for me to be out of work for a few months, we couldn't live off just one income for long. And, DH and I both wanted the option to go to a one income household when we had kids.
We started keeping track of where we were really spending money. Our purchases for books was over $200 some months, eating out was over $400 per month (for two people), we didn't have any credit card balances but we did have hefty student loan payments and some car loans.
What we did: We got rid of extras: call waiting, caller i.d., cable t.v. We trimmed down dramatically on eating out and buying convenience foods; we went to the library instead of buying books. If we NEEDED something, we added it to our list and and bought just off the list. Unless it was an absolute emergency (like a broken car) then we didn't buy anything unless we had the cash to pay for it. We used the Snowball Method to pay off our debt.
In 8 years, we've managed to pay off all of our debt except for our mortgage, we paid cash for some big remodeling projects, and we paid cash for our last car. We've gone to a one-income household, we fully fund a 401k for DH and an IRA for myself, and put money away for the kids' college. We save assiduously for the items that are priorities for us and are able to take one to two family vacations per year.
It is difficult to go from Living Above Your Means to Living Below Your Means, but the payoff is excellent!
Good Luck!
