I think the best thing you can do to prevent yourself from using the card (s), is to shred them! That is what I did years ago when I was so far in debt from credit card bills. By not having them, that stops you from spending. When I did this 11 years ago, I only kept a Visa card and my Firestone auto card in case I needed something done on my car. By shredding, you really aren't closing the account.
