Erin, I hope I don't have what you have. I spent all day tuesday flying to Tulsa, driving 4 hours, leading a 3 hour meeting, then flying back to Houston Tuesday night. I spent all morning yesterday walking at a site walk...and my voice is a wreck. I am assuming it is just all the talking, but yesterday i did feel a bit feverish in the afternoon.
Then I went to spin class last night and did a double spin class...

...about 100 minutes. The instructor forgot that the schedule showed her doing 2 classes last night and she needed to leave...so she left the CD in the stereo and let it run while my wife and I did the 2nd class by ourselves, then shut down and locked up the studio behind ourselves. HR monitor says I burned 1254 calories. I pretty much crawled to the bed once I ate dinner and relaxed a bit.
Now crazy me is about to pack up and head for the gym for another class tonight. I am going to sleep like a baby...
