Avoid Alzheimer's - hold the Provigil?

I've a hunch that this is true - lack of sleep linked to Alzheimer's.

In the past few years there's been a lot of interest in the misuse of modafinil (Provigil). It's being used to extend waking hours rather than to treat narcolepsy.

Maybe this isn't the smartest move ...

Speaking of which, I should go to bed now.
