That's so funny! Well, not really but fatigue is one of the number one reasons MS patients stop working. What was this guy thinking? Oh wait, may be he wasn't.
Anyhow, should you have any trouble or continue to get worse over the weekend, I would to the ER. They may be able to help you more than the neuro did.
In the meantime, get plenty of fluids (juices, teas, and water) as this will help flush your system of the virus. Rest when you feel you need to rest. And take care of yourself by trying your best to relax.
Hang in there, Erin!
