our crew never really did illegal or prescription drugs
But we'd drink booze and/or achieve Adderall-like effects with caffeinated energy drinks. None of us drank coffee so we had like... zero caffeine tolerance. If you have zero caffeine tolerance and you slam multiple energy drinks the effect is NOT subtle
of course, TODAY, my ruined body is so immune to caffeine I can chug coffee directly before a satisfying REM nap lol
Going on a tangent: it takes a while for the caffeine you drink to make it through your digestive system, so even for someone without any tolerance at all, they could take a few shots of espresso on a full stomach and then have about a 30 minute window to have a nap, before the jitter starts.
BUT: On an empty stomach, or even if I've had a little bit of food, it feels like caffeine works fairly instantly for me? I'm the stereotypical "can't function until I've had a little coffee in the morning" type of guy. Is this purely psychosomatic?
