I'm a fan of the Drabblecast, which is dedicated to flash fiction, though the stories are usually not for those with a weak stomach. Norm Sherman does a great job of reading every week, and he usually makes me laugh out loud.
Mysterious Universe is another favorite, and it's basically an overview of strange things going on in the world this week (it covers UFO's, cryptids, ghosts, and lots more). I would be on the EA forums much more often of it weren't for MU. Not that I don't love it here...
I also like X Minus One and The Horror! Both are rebroadcasts of old radio shows. X Minus One is scifi, and The Horror! is all... well, horror. Both generally have great stories, and the old radio commercials in The Horror! are priceless. Once there was one for chewing tobacco, and the jingle included the lines, "There's women in pants, and women in bars, but there's still a way to show 'em who's boss." I had to back it up, 'cause I couldn't believe I'd actually heard that. It was hilarious.
Hope these help fill your time... and I hope you feel better soon!
