I'm 22. I took ecstasy for the first time last weekend. I took 2 pills. I stayed hydrated, I ate and I tried really hard to take care of myself, but now every morning since I have taken it, I'm jittery and my heart is racing when I first wake up. It feels like it's going to beat right out of my chest. Eventually as the day goes on, the feeling goes away, but I can count on it to be back the next day. What really scared me was this morning. I felt kind of a jabbing sensation in my left arm like I was being stuck with pins. Maybe I'm making something of nothing and my mind is messing with me since I'm already worried about it, but I'm just wondering if this is normal or if I should be worried about my heart.
