^^Yep, like me.
Also, I think when you've taken MDMA in the past, your body sort of 'remembers'. Just because you're having a good time doesn't mean your body is happy. It's actually in great distress while being attacked by such chemicals, hence the 'fight or flight' response. So when it remembers MDMA, and the distress it was put under from it, I find it can trigger the same response before you even take the drug! At least that's the sense I make of it, because now after I've abused MDMA, any time I think I'm going to take some, my body starts literally freaking out, shaking, panicking, anxiety, sweating, getting dizzy, nauseus, etc.. Then, when I convince myself "OK, I'm just not going to take it." 100% of the symptoms I just described subside.
It's bizarre, but clear enough of a message for me to take it seriously and shelf the molly for good.
