I have an appt. today and will ask about flouride. It is something I'd planned to do anyway, as I'm a longtime green tea drinker (curently down to a cup or 2 a day, at as much as 6 cups a day prior to this, back when I thought it was "good" for you!) I will get the results of my last Iodine load test and, if I'm not saturated after 7 mos. on Lugols, I'm going to stop the tea completely.
