Thanks Jhan, that was very interesting. I have similar symptoms...
My main symptoms are:
Brian fog/can't think straight/lack of energy
White/yellow stuff on tongue (some of it comes off after brushing)
Eyes hurt (my vision on right eye has gone bad this last 6 months)
Feeling cold and hungry
Slightly sore/tingling back
These symptoms keep coming back... just when I think I've cut out what's causing them, something else seems to cause them!
