upper respiratory tract infection
"I work overnight shift in a hospital, sterile instrument supplies, not patient care. I picked up a bad head cold which morphed into a sinus infection, no fever. Not the end of the world of course, but after 3 weeks and 3 work shifts missed, I went and got it checked out, and was prescribed azithromyocin, 5-day treatment. Within 2 days my sinuses and head began improving but my only complaint is the possible side-effect of insomnia. Again, I work overnight shift, and sleeping during the day is never easy, but I've called off 3 additional work shifts since being on this medication, solely from not being able to sleep enough (less than 4 hours). Even though my head and sinuses are getting better, I refuse to work if I haven't slept enough."
