hello, i am a 58 year old male with symptoms of extreme fatigue. i went to an ent and he diagnosed me with candida yeast infection, with no tests to back up the diagnosis. he put me on nizoral and referred me to a book called the yeast connection. the nizoral is causing severe stomach upset. i checked online and found out that the fda warns of liver problems with this drug and does not recommend it. while i believe that a change of diet is recommended for me (eliminating simple sugars and carbs), i am beginning to question his diagnosis and rx choice. later i found out that this doctor believes that all diseases are caused by candida. not sure what to believe at this point. thanks
