Long story short, I last did MDMA 6-7 weeks ago, and since then was in a depression phase and felt empty etc. However just then, I finished work, tired, sat down, pumped some music and all of a sudden a burst of euphoria just hit me like a train! I could not stop smiling, kept thinking positive thoughts, my eyes were locked on my iTunes for a good 20 seconds at some points, everything just lit up nicely in my view, decisions were made clearly etc etc. What caused this? Was my serotonin levels just back to square 1? Placebo? Or is afterglow just hitting me out of no where?
