If you are around Mudd, and you start suddenly feeling more tired/sleepy than usual, and dizzy as well, you might very well have the random virus going around. I've been told that Bonine is probably the best over the counter treatment for dizzyness if you need to stay awake, say for classes. In general, motion-sickness stuff might help. I don't know how long it lasts, but I do know that there are at least a handful of other Mudders who are sick as well.
