Yeah, it's pretty great when it works, but for me it only worked once out of maybe 6 times I've tried it. It had a noticeable effect on anhedonia and motivation too.
It wasn't even the first time I tried it, maybe the second or third time that it actually worked. No idea why it only works once in a blue moon.
When it doesn't work it just gives makes me somewhat dissociated, apathetic, and slightly dizzy.
But yeah it's one of those nootropics that requires moderation. Not sure if it's even appropriate to label it a nootropic considering its addictive nature in some people.
