Actually didn't Shulgin say take your dose, then take half of that right before you peak for an optimal experience? I may be slightly off, my head hasn't been focased on ecstasy lately, and all the bud I smoke I'm prone to making a mistake here and there.
I'm going to be completely honest, when I took ecstasy for the first time, I was deathly afraid, but completely happy with doing it. After all the research, and experience I've had with it now, I still can't tell you how 'safe' MDMA really is. There's a lot of variables which can effect people differently, such as prior illness, medications, underlying problems which have yet to surface, adulterated pills etc.
Sadly, not enough studies have been done to rule out conclusively that MDMA is safe or harmful, but the first generation of people (late 1970's and early 1980's) who used/abused ecstasy will be our guinea pigs, and we'll sooner or later see the long term effects.
Abuse definitely accounts for most of the accusations that ecstasy is harmful, and people tend to not know what they are dealing with in most of the cases of death or serious injury. Know your body, know your drug, know what you're doing
That was probably the stupidest thing I've ever heard, and if you have any intelligence at all you will disregard that.
