I took some 20mg 2C-D for a club night the other night. That drug is always really perfect for clubbing for me (along with a beer or two and tons of water) - it's so transparent, almost feels like I'm not on anything at all, yet I find so much attention for the amazing music, and energy to just keep dancing and dancing, and pro-social. Even after less than 4h of sleep the next day and week there's no hangover at all. I find it to be like MDMA in terms of partying, but without the extreme love part, just the good vibes part and party mode - and no wreckage after - I reckon you could take this pretty regularly without much negative side effects.
I took it after completing some *very* strenuous exercise that morning, about 3h of running in a trail race half marathon through deep snow on mountain trails. I wasn't sure I'd be able to go out after all that, yet I still had the energy to have a night of my life and dance with lots of energy to the amazing music that night.
It did help that the music was utterly fantastic, right up my alley. It's amazing how good music can help you dig into the depths of your physical energy and just keep going (especially when potentiated with a pinch of psychedelic).
