I really do recommend you get the book "The Tao of Health, Sex and Longevity," and pay attention to the foods/juices he recommends for your specific issue.
He also explains that when you fast, you need to not break it at all until the end. The reason is that your body will immediately quit the detox process the minute you eat anything. It is a nice, down to earth explaination. You should be able to get the book from the library.
I htink you're off to a good start. Stick with it. Keep putting the healthiest things into your body that you can, and do your best to avoid foods that are processed.
Keep reading this website too, and look into doing a liver cleases. They are cheap and simple, and very powerful!
