I do research when I'm sick, about my sick.
I'm a librarian, not a medical professional, so don't take my advice -- just use it as a starting place for your own research! In general, I like expert reviews and meta-analyses - they do the hard work for us, take advantage of it.
I just got over a cold, so I'm starting this blog with a page on
Respiratory Tract Infections. Mmmmm.
