I did X once...... The only time in my life where i wanted to live forever one hour then contemplating suicide the next. Total craziness!!!! But anyways, i remember hallucinating on it. The hallucinations were present for the next day after rolling. We listened to fischerspooner while we were rolling, and i was hearing the same songs in my head over and over again for 18 hours straight! I was also seeing reflected visual effects from rolling (we had blacklight effects while rolling, and i hallucinated them after the comedown)
