JB, welcome. It's good you are reading Pagano's book. Some folks have had success with Pagano's program, however most probably have not. Having said this, few can strictly adhere to his diet and his colon care regimen (colonics, enemas). And some of this theories are a bit "out there". Although I feel Pagano's book should be required reading by all psoriatics I consider what he wrote to be more inspirational that something one would live by.
Pagano's book makes for a good starting point. You have a long and interesting road ahead of you.
