Thanks for the info ladies! I get cold easily after I ride as well. I especially noticed it this winter when I was doing rides in fog and 40 degree weather. When we would stop at our mid point coffee shop, I would go into the bathroom and use the hand dryer to get my clothes dry and my skin warm so I could get home comfortably (it worked). I don't seem to hold heat very well! Especially since I have lost so much weight.

I'll look up the syndrome-never had a name for this condition. Used to get this way after running marathons as well.
