Some evidence seems to indicate you did the right thing. Anecdote: I do the same thing now (embrace the fever); I let my body overheat; I’m convinced it shortens the total suffering

That said, the discomfort of a 10+ day flu vs slightly reduced immune response, I'd take the medicine any day.

Well, I'm a believer now. When it comes to fevers ibuprofen appears to be incredibly effective. I took 800 at the peak of my 102 fever, and within the hour, my temperature was back to normal. Amazing stuff.

Tylenol and ibuprofen are very transparent. There's no obvious effects to remind you that you're on it. Yet multiple scientific studies have shown that the two in combination are just as effective for relieving some kinds of pain as Vicodin.

I can't count the number of times I took Tylenol and 800 of ibuprofen then told everyone at work I was feeling 'better', only to train wreck at the end of the day and feel just as bad as I did that morning

For example, I caught the Coxsackie A virus (“hand, foot, and mouth disease”) from my toddler a few months back, and it got in my gums and made them swell up very uncomfortably for a week. Ibuprofen significantly reduced the inflammation.

Advil and Tylenol can be used when the body can't effectively lower its temperature on its own. My understanding is your temperature rises to kill the virus and sometimes your system loses control and that is when folks get into serious trouble. The medication will help lower your temperature.

I think the most important thing to consider is Starve a Fever and Feed a cold. Do not eat anything sweet ever during any kind of fever. It will fuel it like gasoline on a fire.

My Grandmother lost both her parents when she was 2 years old in 1918 to what they said was Pneumonia. I suspect it was the flu.
