Interesting. It so happens I took provigil (modafinil) more for this reason than for sleep deprivation or to cram in more all-nighters in college. The experience was like caffeine, but without jitters or noticeably increased BP/heart rate. It was more like "hyperawareness" without hyper-vigilance or anything unpleasant. ("Limitless lite.")
I tried adderall for concentration at a standard therapeutic dose, but the jitters and palpitations.
These days, I just use mirtazapine (depression) and flonase (sleep apnea) and occasional caffeine, and all is sweetness and light.
EDIT: If anyone can add peer-reviewed, reasonably-safe, well-studied neuroenhancement lifestyle choices (food, supplements, pharma, etc.) that aren't just spam/gimmicks, that would be interesting.
