There is a great book by Melody Beattie called "Codependent No More: How to Stop Controlling Others and Start Caring for Yourself" (you can find it at the library) that was suggested to me by my psychologist that has really helped me deal with my co dependency issues.
I really don't think that there is a "quick" way to "cure" co dependency, I personally think that it needs to be a "steady" learning process one goes through. You didn't get the way you are overnight right? so you really shouldn't expect it to be something that can have a "quick" cure.
I was able to get a book on CD version and listened to it while I drove to and from work. It really helped me open my eyes to WHY I do the things that I do and the feelings I had associated with my co dependency. If your a busy person- I highly recommend the book on CD/tape version.
Another suggestion is to get connected to a therapist, counselor, someone you can talk to about the issues you are having. For me personally, it just made me feel better knowing that i had an outlet to get my frustration, depression etc. out in the open to someone who wasn't going to judge me for my feelings, but would understand where they were coming from.
I really hope you will consider my suggestions.
Good luck to you.
