I pretty much stopped taking MDMA / MDXX in about 2000, Ive taken crystal a few times since but not in quantity so I can't comment on all this precursor talk.
What I can say is that dancing like a fukin loon was the mian attraction for me, I'd been into Northern Sould and such and loved dancing. The underground party scene took that and made it something special, add in MDMA and for me it was everything and more.
I really avoided sitting about to much, nice to have a break but monging out didnt appeal, often others would be saying the pills were 'mongy' / 'smaky' (yeah right) and I'd be rushing like a jet fighter. Thos high dose MDA pills floored many, I knew what ws in them but others were convinced they had some tranquilizer in them or some such shit. You had to make the effort to immerse yourself in the music to really get the true synergy of the drugs and the rest, loved the tripped out bliss of MDA or the total hyperreal paradise of good clean MDMA but I never really enjoyed it outside of that environment.
