Amazing for a burst of creativity, motivation and brain energy to do and try new stuff.
Decrementally slows down your body and mind after ~2 hours in my case.
Very hard to concentrate, music affects a lot on the HigH.
Doesn't make me very hungry, but looking for something to do, hard to close my eyes because of boredom.
Feels tired like I had a long day, kinda like mind fatigue and a little body fatigue than sleepiness.
