influenza
"I became very ill with severe vomiting, diarrhea, headache, fever, chills, aches, exhaustion...and I had a 5 month old baby to take care of. All this DESPITE the flu shot. Twelve hours after the initial onset, my doctor diagnosed me with the flu and prescribed Tamiflu. It slowly got better, and two days later I am some what functional...which is good, because now I have to take care of my baby AND my sick husband. We'll be getting him Tamiflu, too!"
