Cant pee whilst on MDMA

[LearntYoung]

Turn on some running water in the bathroom so you can hear it, close your eyes, and try to relax. The reason it's harder to pee on MDMA is that it increases ADH (anti-diuretic hormone), but I realize that wasn't your question.

An increase of ADH would increase the amount of urine ending up in the bladder, because there's less water reabsorbed into the body... Besides, you can feel your bladder being full sometimes, while you really can't manage to pee. I think the biggest problem is contracting muscles, that hold up your stream.
