I just woke up after sleeping for 14 hours. Prior to that, I spent 2 hours laying on the floor of my office too nauseous to walk to my car or drive home safely.

My wife (a nurse) was told there's a nasty GI bug going around right now. It doesn't change the fact that it would have been wise for us to descend Saturday afternoon, but it seems some of the symptoms were likely caused by something other than AMS.
