I have not long started on the Paleo Diet, but from the results I have seen so far I am not going to stop any time soon.
Having a "sweet tooth" I found it a little difficult at first, but then I found that I was really wanting to eat fruit. Probably a natural body reaction to wanting sugars.
I got most of my information from one site - yourpaleodietplace.com - it seems to have all you need to get going.
