Very strange. You can't urinate on it? I can urinate and even ejaculate on it no problem - which is always difficult a few hours into a heavy MDMA experience.
How many of your symptoms would you put down to placebo?
A long binge/OD on this stuff could possibly lead to stroke/heart attack/kidney failure.
It would have to be a fuck of a long binge to lead to kidney failure for me as I can urinate perfectly well on it. I'd recomend keeping to a sensible dose less than 200mg but unless you have other health issues I have grave doubts it will cause a heart attack, and even less likely, a stroke. I don't think it's any harder on the body than MDMA and there's no urge to redose which makes it even safer - and MDMA isn't what anyone could call an "unsafe" drug.
I don't think placebo was a factor. I normally am free of CVA tenderness or an inability to sweat/urinate for hours

. 6-APB is more likely to have effects analogous to MDA than MDMA, which can (like MDMA), cause illness and death through a variety of mechanisms (epsecially in women). Although it is entirely possible that my symptoms were the '1 in 250k' allergic reaction, There were plenty of experiences with the aforementioned substances without serious consequences. You may also keep in mind that I exercise about 10 hours a week, sleep normally, and have never ever had the symptoms I experienced that evening. A couple of points I want to make clear:
1. I took a combination of 5 and 6, not just one or the other alone.
2. Wiki 'urination,' read the neuro section a couple of times, and then holler back at me. Your experience is just as viable as mine, because neither one of us has proof, but I get the feeling you might not understand how dangerous an inability to urinate or sweat after dancing for several hours may be.
I'm not trying to alarm anyone, but rather inform those who may be interested in potential side effects of new drugs they leisurely imbibe. I predict we will read more experiences like these in the coming months. It's unfortunate really, because it was pretty damn fun in spite of the side effects.
With regard to the other fellow's question about urination, pissing is a result of interplay between your motor and autonomic parasympathetic and sympathetic nervous systems. The wiki article is a pretty solid explanation. These functions can be altered by changes in basal metabolic rate, temperature, psychological conditioning, and.... lots of shit. Stimulants generally tend to excite the sympathetic nervous system via an in increase basal metabolic rate, which lead to changes in temp, psych,

and pissing

. We could all get smart and describe the exact neurological conditions leading to a piss, but I simply don't have enough time to care. Made 530 bucks tutoring anatomy this weekend and I'm ready to go to sleep.
So.. sleep tight, and BE SAFE!
