Through trial and, well, trial, I have found that I feel better on a mostly carnivorous rather than herbivorous diet.  But when I did away with wheat, I craved it.  In the ER4YT book, they recommend Type Os avoid oats as well as wheat.  For me, that was the factor that was missing for me.  I stopped eating my usual bowl of oatmeal for breakfast.  Within a week, my wheat cravings were gone AND I almost knocked myself out stepping out of the bathtub:  I had gotten into the habit of using an exaggerated motion to bend my knee and lift my leg to get over the edge of the tub to avoid once again smashing my shin or foot against the tub.  I hadn't realized how much my overall joint inflammation had gone down, and range of natural motion improved, until I nearly knocked my knee into my chin after a week of no oats.  No more bread/cookie/pasta cravings, reduced inflammation, and better range of motion are what I got from this diet.  Well worth the price of the book for me.
