Okay. I do molly(MDMA) every once in a while. Yesterday i went to my dealer and picked up a half a gram rock of what i thought was pure white mdma. I put it underneath my tongue how i normally would but my entire mouth started going numb. I didn't think much of it at the time. But then wen i started to feel it it didn't feel like roling.. Whatever i took made me space out.. I would randomly twitch my pupils were HUGE.. I had really bad tunle vision. My eyes felt like i couldnt keep them closed.. Everything was making me paranoid and randomly my entire body would freeze up... I was completely aware of my surroundings.. It almost made me think i was smarter.. Instead of wanting to go party like i normally would on mdma i just wanted to sit and do nothing but blankly stare at things.. About halfway through the high, i felt like no matter what i did i couldnt get comftoradable. Hours flew by like minuets at first i liked how i felt but then i started feeling terrible. The thought of food made me sick to my stomach even though i was very hungry. Later that night when i desided i needed to sleep. I laid down.. Then i started hearing a really loud ringing noise. My heart started racing. It almost felt like someone punched me in my chest. It felt like i was having a panic attack everything felt fogy. I litterly thought i was going to die. Then it just stopped and i was fine. I kept trying to go to sleep because i was very tired but at the same time i was wide awake. I eventually fell asleep. I had a hard time sleeping. I kept waking up because i would twitch. When i woke up this morning i was still feeling it slightly. It slowly wore off as i went through my day. But my entire body feels weak and my throat burns.. I have no idea what i took. But i know it was not mdma at all. Like i said it was a half a gram rock and it was a pure white Color i thought maybe it was a crack rock but can crack last around 20 hours? My friend thinks it could have been meth.. But i really have no idea... If somebody could please tell me what the hell i took? I really do not like that i don't know what i took. Please and thankyou
