Ugh, I hear you. I just started Geodon and now I sleep like the dead.....hoping I don't sleep through my alarm, like I did through my husband's three attempts to wake me up this morning.

In your situation, I'd simply say you woke up nauseated and feverish. It's really none of the employer's business what your health issue is, but they don't like it when people come in with something communicable. Call it a 24 (or 48)-hour stomach bug.....there's lots of that going around this winter.
