I had a fever, my head felt like it was going to explode, my chest felt like someone was trying to pull out my heart and best part was, I had work to do, it was month end rush like every other month, and being goody-two-shoes who hates to throw more work on others who was loaded with their own stuff to finish I work my full 9 hours that day and came back the next (on a weekend) to insure that all timesheets were entered for the staff, that there weren't any missing, cause then they'd not get paid and I'd feel even worse than I did sick as I was, when everything was in order (after another 6 hours), I left slept the rest of the day away, and the next and came 1st day of a new work week (hoping actually was still at least a bit sick, so I could go to the doc get booked off and use my sick leave for once...
I was healthy as a spring chicken running on adrenaline!!! Like really? Couldn't I have had the worst cold of my life just the next week when all the work was handled and I got take the it off with sick leave??? Spent some time watching sib movies, under a think blanket and eating ice-cream (usually the only thing I can keep down when sick; being deathly serious now!!!) Thus here's my tip
When I had trouble swallowing (Was working as intern when got sick - a previous time); I ate and "drunk" frozen stuff - Frozen Yogurt, Ice cream, I even made chocolate milk, put it in the fridge and just before it freezes over completely I would drink/eat it (like a slush-puppy) anything warmer than "freezing" I couldn't eat or drink, for the life of me! Soda burned my throat and besides that it felt like I was chocking, same with any other food. I even ate my soup frozen...
So try that.
