Interesting. I started biking to/from work and was wondering why going home always felt harder. I suspected it was because my body was a bit tired just from being awake for the past ~8 hours (desk job, so not the work itself) but I never considered mental fatigue to play a part.
I wonder if this extends into the positive as well, do cognitive boosting drugs (nootropics?) enhance your performance.

Yes. Dextroamphetamine is considered a PED and is banned in (some? all?) professional sports. The Orioles' slugger Chris Davis was suspended a couple years ago for using it. But it is a CNS drug; I believe it is most commonly prescribed to people with ADHD, to improve their focus.
