Dear Claythrow I have experienced this a great deal, even without chelating, sometimes I don't feel too bad during the day, but especially at night. I feel like my temperature has soared and have terrible nightsweats and inbetween chill and fell achey and feverish. It just seems to come in waves and is very draining, then in the morning, because I probably get about 2 hours sleep I feel weak and exhausted. Sometimes the waves of this come during the day, but I have had this since first becoming ill 3 years ago and since removal it hasn't changed, it's almost like having the flu. I havn't got any better really and am at a point of not really knowing what to do. It's almost like there's a continuous virus going on that your body is trying to fight off. I can empathsise.
