I know detoxification sounds like something Hollywood stars do before their big red carpet events, but for me it hasn't been glamorous at all. It feels uncomfortable and I have to be careful and work with a doctor along the way. Even then, I still have to make sure to listen to MY inner voice on what is best for ME.
I don't really even like the word "detox" because we tend to think the purpose of it is to starve for a few days to lose lots of weight. But that is not how I have come to understand it. Detox, in my world, is the process of slowly assisting the body in the removal of the icky stuff that is keeping me from healing. In my experience, it's a principle that has required faith, because it is difficult for me to see the results immediately.
The best book I have read on detoxification is called "The 7-Day Detox Miracle", by Peter Bennett, Stephen Barrie, and Sara Faye. Don't let the name fool you! If you have chronic illness, you will NOT get better in 7 days or anywhere near that. For me, this book should be called "The 70 x 7-Day Detox, Long and Arduous Miracle". But nobody would buy a book with that title so I guess they were smart. This book has really helped me understand important concepts and I have found it most helpful for me to implement some of the basic ideas carefully, as my body can tolerate...I do a little, then take a break.
