While not actually an endorsement, Ray Kurzweil mentions Modafinil as well as Donazepril in "Fantastic Voyage."
Now, considering these are both controlled substances in the US, I wonder why he would mention these and not some more readily available alternatives."Modafinil (Provigil) is FDA-approved for the treatment of narcolepsy, but many college students have found it can help them focus while studying for exams. Others use it as a cognitive enhancer; they find they have more energy, need less sleep, and can work and play harder when they take it."
Are there some good alternatives or weaker legal versions? Do any of you have experience with Modafinil (known also as Provigil or Alertec in Canada)? I am interested, but not if it's going to cost $140+ because I have to obtain it outside the US. [huh]
