got the flu a few weeks ago and was prescribed (and did purchase) tamiflu, although it was expensive. i did some internet reading and apparently tamiflu only works within 1–2 days of symptoms, and even then only helps you get better 1 day (!) sooner than you would normally. i was about to not take it but it also apparently helps to prevent complications from the flu (like pneumonia), and my doctor had said i was at risk for that. not wanting pneumonia, i took the pills. the other 2 times i’ve gotten the flu however, i’ve always toughed it out with basic painkillers and emerged fine after 2 or so days.
