I also have the book, and have to admit that I failed miserably. It takes a lot of planning, and you need time. I suppose that once you do it, it would come easier and faster. I have tried the LSA mixture (linseed, sunflower and almonds) and my psorisis does seem to be getting better.
I do still want to try it, but not right now.
Maybe it would be easier if we both did it at the same time?
