I am about 50/50 on his book ,some of the presciption medications in his book that he mentions can be dangerous and he does not mention that the withdrawl symtoms from some of these medications can mess you up for a very long time ( for example hydrocortisone if taken for 6 monthes can shut down your adrenal gland production for up to a year in some cases and anti depressants have a down side also ,I know I was on 5 different types of them on and off for about two years untill I found out what was really causing my problems MERCURY !!!!!!!!) ,but symtoms section in the book are very desciptive and correct you have to give him credit for that. all and all I am glad that there are people like him, huggins and russ tanner that are willing to put there neck on the line to inform so many of us who are dealing with this murcury issue and give us hope
