a diary of dates re symptoms.
Giardia nasties have a Life cycle of about 4-5 days. It can take many tests to catch them active & that is why so many tests don't show anything. I kept track & finally was perscribed medication (can't remember what - it was 15 years ago - & in Aus) at last visit to doctor. Coincidently that test came back positive.
