The white "crap" on the tongue could be yeast related as well. but interesting enough I did some acupuncture w/ a chinese doctor who uses tongue diagnosis who told me that the white "crap" was indicative of a toxic liver. Toxic livers are always going to be a consistent fact w/ people who are battling immune situations in that the liver is going to process 1) the immune factors ((cytokines etc.)) 2) endocrinological factors - responses due to immune create mucho oxidation 3) american chemicals, preservatives etc.
