Oh yeah...chills in 100 degree heat- that's exactly what happened to me last year.

Missymay, I've been told that one of the best ways to tell if you're drinking too much or little is to weigh yourself before and after a ride. Small variations aren't going to tell you much, but a 6 lb gain/12 lb loss is indicative of a water problem. I've read that drinking too much can be dangerous, so that's what I'm trying to avoid. Who knew that water consumption could be so complicated???
