Grrr....I posted on this earlier (and forgot to submit reply). I just wanted to add that I have never been a 'sweater'. In the heat, and when exerting myself, I just get more and more uncoordinated, more dizzy and brain foggy. My face glows red like a beacon - sometimes I even go to the bathroom and put water of my face, neck and arms (then I realise how much difference it would make if I did sweat.

Regards
