I've microdosed psilocybin just because. I wasn't more productive but it was worthwhile, I think.

Would love to try LSD microdose to see what happens.

Creative productivity? Or do you mean performining at your job?

i mean, it helped me stay awake and on task for 24+ hours, so i was productive in the sense that i finished the paper i was writing. did it increase my creativity or enjoyment of the project? nah. i basically used it for the stimulant effects it has on me. 5/10 experience, might microdose again under different circumstances, like doing art. overall, my thoughts can be summarized by what Defasher posted. not a huge fan of lsd for productivity.

I might give this a try tomorrow.
