I have been searching the internet trying to find an answer to this very question, hence came across your discussion. I'm not exactly in East Dulwich, Melbourne Australia actually. I have to say thanks to the Minkey - I have been labouring under a fluctuating but generally just sub 40 degree temp for a couple of days, (monitoring my temp often to make sure it's not > 40) there is a dreadful lurgy going on over here too and it's Autumn and hot. I have been trying not to take paracetomol to lower the temp, except at night to help me sleep, having heard before about fevers being the body's best defense mechanism. The Minkey's answer is exactly what I have been trying to find out. Feeling better today so think I may have cracked it! Could of course just have been coincidence and the fever had run it's course but it worked for me. Hope you are feeling better Brum.
