influenza
"I tested positive for flu on my second day of being sick. The doctor told me I MUST eat something before taking tamiflu or I could possibly have violent vomiting. Even though I was very dehydrated and nauseous already, I managed to eat a few saltines with ice chips. The only issue I had was strange dreams. By the second day of taking tamiflu I felt 80% better. Highly recommend but difficult to get unless you test positive."
