Hehehe I dunno... I remember this one night when I dropped 1 bikkie, had some coke, dropped again, more coke, followed by another drop and a few points of speed...
I can safely say that THAT was a fun night! Lol! I felt the effects of everything evenly, but maybe that's because i had a LOT of MDMA (for me, anyway)... I normally have 1 pill in a night, so I tripled my usual dosage. The speed made me rush quite nicely, and the coke seemed to have that "on top of the world" effect.
I was standing outside the event walking around all pumped-up coke style, and telling people they were wicked and awesome n all that kinda stuff....
MESSY NIGHT, but fun nonetheless!
