I know what you mean... For less than a few hours you feel like a double 'ard Belgian bastard... But after that I get really cold and have a little weep coz I'm actually an English fairy.
I agree- especially in Summer. Though I get the feeling that riding yesterday (in totally inappropriate clothing) may have contributed somewhat to the illnessness today.
Good luck mate. I broke myself this morning and will most certainly not be joining! You love a soggy ride dontcha (rule #9)!?!?
