So start with the book Sugar Blues. My mother bought this book in the 60's and still swears by it, passing it out to friends and family.
I also found another book called Get the Sugar Out: 501 Ways to Cut the Sugar Out of Any Diet.
Then check out these videos I found. You don't need to watch it, just turn up the volume while you're working at the computer and listen! In fact, listen to it over and over again.
