I have a prescription for Provigil for jetlag, but like the author, I'd found non-prescription channels for it before.
I've found it excellent for combatting tiredness, and it can improve my focus, but nothing like the Limitless-esque drug the author talks about. Admittedly I've only taken 100mg at a time, but still - about 5 hours after I take it, I tend to become cranky. I get obsessive about things, rather than focus, and if my obsession falls on the wrong thing, I find myself having wasted 6 hours on writing up or investigating some hare-brained business scheme, rather than my work.
I have easy, legal access to it, and I only take it these days if my sleep is majorly disrupted. If I was getting the benefits the author was, I'd take it every day.
