Limitless. Go watch it if you haven't

Limitless was based on Modafinil (a real-life nootropic you buy). You can read more about it here: http://www.brightjourney.com/q/physical-hacks-diet-nootropic...

I asked Alan Glynn (the author of The Dark Fields / Limitless) two days ago on twitter if he had based it on Modafinil. His reply (in a public tweet):

"Thanks - no, all made up, wrote it nearly 15 yrs ago, before I'd heard of modafinil, certainly before the nootropic boom."
