influenza
"Woke up at 1:30 am yesterday with a horrible headache, severe body aches, chills, and low grade fever. I felt like I was going to die! I recognized the symptoms from having had the flu 2 years ago so was at acute care when they opened at 8. I was tested positive for influenza B and prescribed tamiflu. I took the first dose around 10 and felt nauseous because I took it on an empty stomach. I took the next dose with food and felt better. I felt almost completely better by my third dose that I took this morning and by my 4th dose I am completely without symptoms."
