We have an answer:
I did stay home today because my stomach ache and gagging last night turned into a full night of throwing up (mostly dry heaves) plus a nasty cocktail of symptoms. My body was spent when I woke up at 6:00 this morning and it felt like I had not slept all night, even though I had been in bed since 21:15 minus the times I was anchored on or over the john. I called in just before 7:00 and went back to bed and didn't get up again until almost 10:30. I'm starting to get better, I think, just now down to a severe headache, but I'm still going to take the rest of the day off and go in tomorrow. If this affects my job then so be it.
