Flu might cost me a job

Hi ladies.

I got a nasty bit of flu recently and have barely eaten or drank anything in days. I first got sick Friday afternoon, and I still have a cough and touchy stomach today. It's Wednesday. I missed too much work because it was go home almost immediately or vomit on the floor. I go back in Thursday from my days off and pretty much have to hope my boss likes me enough to keep me in spite of being sick too much.

The thing is, my stomach is still easily upset and half the time walking slowly is enough to upset it. I am on my feet all day and at a rather fast pace at work, so I can't eat anything if I want to avoid getting really sick, but I'm hungry. I've dropped about an inch from not eating, and I'm so lethargic, I almost fell asleep in class today despite over eight hours of sleep, even with my stomach gurgling ominously.

Do any of you have ideas on food to eat or how to settle my stomach? If I keep my job I'll be working tomorrow and I need energy, as well as to not vomit on the floor or my boss's shoes during our meeting.
