I had Flu for an entire week. Took Tamiflu, but the first few times I took it wrong so I was constantly vomiting. Just a warning, if you get Tamiflu, TAKE IT WITH SOLID FOOD LIKE CRACKERS, AND NOT A LOT OF WATER!
Oh my god it was bad, my face had purple dots from all of the blood rushing into my head when i bent over the toilet to puke ;-;
