did you realize that sushi made you sweat at the time it happened or is this in retrospect? personal health awareness is hard to come by sometimes(see lilyponds post above). i think its easier for women because they get in tune with their bodies more. OTOH, some women are convinced they properly interpret what they perceive. men have to learn it from scratch and dont carry such expectations.
your body has been screaming for Iodine for a time, eh?
