Sleeping With a Sleeping Disorder
It's a bit odd, to be honest... some of the stuff it says about narcolepsy is a little questionable. What I found interesting was that it says that narcolepsy is a very serious illness and shouldn't be joked about. Why not?? I don't really find narco jokes offensive. Especially that narcoleptic dachshund.... oh man that's funny. I mean, yeah, it's serious and has specialist doctors and heavily regulated drugs and its effects can be life-ruining if not handled properly, but that doesn't mean it should be exempt from people joking about it. If I didn't see the funny side of things I'd be bloody miserable!!
Anyway, it's an interesting site nonetheless. Get past all the ads and nonsense and it has some interesting tidbits in there.
