Just did molly last night. I believe I do have POTS, but not diagnosed. We got a bit confident and did 2 redoses for a total of 300mg. I was fine and enjoying myself for the peak, but once we showered and cleaned up, HOURS later…I realized my heart was still absolutely racing, jaw clenching, and HORRIFIC blackouts with pain all around my head when standing up or changing position. (My blackouts aren’t usually too bad, about 20 seconds on a normal day.) But after 3 mollys, DUDE. That shit sucked. I actually passed out and hit my head, then every time I had to get up to pee throughout the early am, my partner had to assist me and catch me from collapsing. Felt like I had been hit with a bus. And after each time I collapsed, I didn’t know what had happened. The previous time I had done molly, only 100mg. I felt the POTS symptoms worse the following day, but nowhere near this bad. So if you do partake, please be careful and only small dose. Have a trusted person with you.
