I am in the process of reading Dean Dwyer's book Make Shi(f)t Happen. I cannot recommend it highly enough. Dean's book is about what to do when your initial excitement about the Primal life wears off. He believes that most people need to make huge changes in their thinking before they can truly and permanently change their health. The book contains some really amazing strategies for this purpose.
Personally, I have hit a mental wall of Bedrock (pun intended). I have gained and lost the same 20 pounds over and over for 6 months. I am in a high wt. place right now and honestly feel awful. I know how to eat and exercise for optimal health. Now it is time to get the mental/emotional stuff worked out.
