I saw a documentary recently (Australian TV) which described a rare genetic
condition in which the sufferer suddenly became unable to sleep at all. No
drugs or other treatment were able to induce sleep. The sufferers lived for
about 6 months (I think) without any sleep and finally died. I'm a layman
and am afraid that's all I recollect.
